Asylum/IoD Joining Problem

[cloudy rippah]

its really weird how this works actually, I have to change between "Allow all files from server" and "Do not download any custom files" for example I'll be on allow all on TTT, then I go to lobby and if I try to join asylum it wont wont work, so then I need to change to Do not allow any. It's very odd, its done the exact opposite as well, not allowing me to join with do not allow, then i switch to allow and I can join.
