I was never sent a serial number
*****
Most likely a spam filter somewhere along the line decided your receipt was spam, and incorrectly deleted it. Please check through any spam filters you have setup. Also, look through any receipts from your order.
GL Golf won't accept my serial number
*****
First, delete the contents of the serial number box in the registration window. Next, copy the serial number exactly as shown in your receipt and press the Enter Serial button. If the screen shows "Invalid Key" you have most likely made an error, make sure all similar characters such as o/zeros and i/1s are correct. If you receive another message you may need to enter you previous serial numbers first, for example the expansion pack serial number will only work if the normal GL Golf serial number has first been entered. Subscription pack serial numbers will only work if the combo or course pack serial number has first been entered.
GL Golf crashes and quits
*****
When GL Golf crashes you might see a screen similar to the first screenshot below. If you press the Report button, another screen will come up where you can copy a large text field (in the second screenshot below). If you copy and paste that into an email to support@nuclearnova.com it will give me some valuable information about where the program crashed.
Alternately if that screen doesn't come up, the crash logs are normally located in your home folder -> Library -> Logs -> Crash Reporter folder, it should be labeled something with "GL Golf " in it.

GL Golf hangs and doesn't quit
*****
First, try deleting your preferences . If that doesn't fix the problem, please send a DETAILED email to support@nuclearnova.com with information on how we can recreate the problem. These bugs are much tougher to fix because GL Golf never actually quits and leaves a crash log, so the more information supplied, the higher the chance the problem can be fixed.
GL Golf runs slow
*****
First, try to quit all other programs to free up system resources for GL Golf. Sometimes a system restart can help restore the system to its normal state. Next, make sure the graphics settings are not slowing down GL Golf, features such as FSAA and anti-aliasing can really slow down GL Golf. Try reducing the window size, this can also increase performance. A preference reset should be the last resort if the game once ran fast on the same computer. Old computers may struggle with GL Golf, this is a hardware limitation that may not be able to be fixed.
GL Golf won't remember my serial number
*****
First try deleting the game preferences. Next, try repairing your computers Permissions in the Disk Utility tool located in the Applications->Utilities folder.
I can't play all of the courses
*****
The standard version of GL Golf is $14.95 and only includes the first three courses. The other courses require the expansion pack to play, which is available at http://nuclearnova.com/register.php for $12.95. New courses released after purchasing the game require the subscription pack to play. The subscription is $9.95 and allows you to play all 4 new courses released in the next year, at a rate of one every three months. If you don't get the subscription pack you are still welcome to download any updates that are sent out, but the new courses will not be available. If you are interested check out the nuclear nova store at http://nuclearnova.com/register.php
I just bought the subscription, where are my new courses
*****
The subscription pack gets you the next 4 courses that are made over the next year. They are released every January/April/July/October. These courses are not done yet, but as soon as they are ready you will receive an email with all of the information to download the new course. Once you enter that serial number you will be all set in the future, and all you'll have to do is download the link included in all update emails.

Text doensn't appear on my in game score card
*****
Try resizing the GL Golf game window, sometimes it can get to narrow and the text disappears. Do this by dragging the bottom right corner of the window, or using the Graphics->Resolution menu option in GL Golf
Deleting GL Golf preferences
*****
To delete the GL Golf preference file, first open your hard drive, followed by the Users folder, then your home folder (mine for example is labeled "jake"). Next open the Library folder, followed by the Preferences folder. Find the file called GL Golf.plist, and drag it to your trash. The next time you open GL Golf, your preferences/best rounds will be gone and you must re-enter your serial number. If you purchased the Expansion or Subscription pack, make sure to enter your GL Golf or GL Golf Combo pack serial number before trying the Expansion or Subscription pack number.
