[LenniSac'em]

Hello, sorry if im posting in the wrong place or theres aleady been a thread on my problem

 

i can't play JediKnight2 (outcast) after installing it, it comes up with this even when the game disc is in the computer

 

other info: the disk is from Star wars best of PC

 

please help

I believe the first disc of Best of PC has EAW and KOTOR on it, while the second had JKII and some other stuff. So I would say, try inserting the disc that has EAW and KOTOR on it when launching jk2 and see if that works.
