it's becouse you use the h@ck from hax. . . , you know better from where...that free h@ck it's a trojan and have keylogger inclus....
my suggestion is ....to reintall windows with FULL EREAST HDD , after that all info from you'r account Yahoo / MNS / CrossFire and other to change the passowrd put on all ....a new passowrd.
You can play Cross only after reinstall the windows .
