got a window on a second story? or maybe a bridge nearby?
lol, sorry but honestly, if you have no firewall or AV software running, there is no reason why mIRC wouldn't work.
Does mIRC run on a 64bit OS? Is your OS 64bit? I can't think of any reason why mIRC wouldn't run on a clean machine (newly installed OS with nothing on it) besides operator error.
hrm its most likely the OS that i can think of. um im not sure if its a 64bit os, its a dual core amd. i dont think it is because ive had it workin on this same machine b4... =/
