Wassup W/FT???

Can anybody tell me WHY I get a perfectly healthy/good screen at FT when ever I log on and reg. for the CC FRs BUT when ever I try to play in any other FT FR my screen goes all KAFLUEY??? I mean, I can log on at 1st, but come game time, not only does my screen go CRAZY (I don't get the hands or bets-NOTHING) but it freezes up too! And after I re-boot it and everything else I can think of, I can no longer even log on!!?? Does this happen to anybody else?? Or can anyone tell my why it would act like that???
