The problem is this. You install ATTAC and then create a game and the game data file is placed near the shortcut and not near attac.exe. The reason is this. The install script did not create the shortcut correctly. There are 2 possible solutions to the problem.
Solution #1: Delete the shortcut and then make a new one

To make a new shortcut, right click on attac.exe and drag it to the desktop then choose create shortcut.
Solution #2: right click on the shortcut and set the target to the the directory attac.exe resides in. Currently, it is blank. for example if the attac.exe is in "c:\Program Files\ATTAC\attac.exe",
then the target should be "c:\Program Files\ATTAC"
This will be fixed in the release of beta3.
It is important that if you do fix this... you need to move the data files from the shortcut to the directory attac.exe is in or attac v4 will not find them.
