Oh, before i forget: if you want both the regular JJ2 and TSF, do NOT put them in the same folder. I was foolish enough to put both versions in one "Jazz2"-folder. Because of that, i could only play online in TSF, since both versions use a jazz2.exe file, and the TSF one replaced the regular one in my case.

You probably won't be dumb enough to do that. but still i can't emphasise it enough: make two seperate folders. It took me a long time before i realised why i couldn't join all those "grey" servers, and i don't want it to happen to anyone else
