Don't beleive it, went home the other week and realised I still have this problem on my pc. Just screen freezes when I F10 + X and then unfreezes but doesn't load xfire window. Game paths are fine, people can even see what server I am on I beleive too.
Normal xfire skin, windows vista, everything running as administrator, tried running uo in both XP compat. and default but no luck.
Lemme know if any1 knows / hears of a solution.
If not I'll just have to try a cod re-install nxt time i'm home.
