Im getting an error message when i try to join a mulitplayer game. The exact error message is:
invalid game folder
do you know why this may be?
Well it could be because the host is using a mod or level that you haven't got. (I take it you're referring to Jedi Knight)
Are you sure you haven't renamed/deleted/moved any of your JK program folders?
A mod would just bring up a checksum error.
Just re-install and everything should be alright.
