* Some of anti-virus programs find the file named cmdow.exe inconvenient which is helping cd menu to run but i assure you its not a virus, dont worry about that. Besides a broad explanation about this subject can be found here
* If you get TrojanDropper.Win32.QuickBatch.c error about kur.exe just ignore it. after you click install that file operates, and since it makes installation secretly anti-virus programs can sense it differently. its not virus or trojan. after installation finished file is useless.. can be deleted if liked.
* You must direct the folder adress of Jedi Academy Correctly.e.g.: "C:\Games\LucasArts\Star Wars Jedi Knight Jedi Academy/"
* Never direct to "gamedata or "gamedata/base" folders otherwise demo won't work and you will get an error.
* Empty the base folder. make sure nothing has left except the original files. (assets0.pk3 - assets1.pk3 - assets2.pk3 - assets3.pk3 )
* To get hints about the levels check out the "Options > Tips & Tricks" part in CD menu.
