Hi, I had some problems too with bypass but I managed to solv it. First of all I have Kerio Personal Firewall. Well ... it blocked proxifier , dont know how but it did. So I suggest you turn off all firewalls ,and maybe anti virus systems also If needed.
Btw: There must be only 1 rule, but CAN be more applications in it. I mean if you have more gameguard files you should add them to the rule. For example: game_guard.des, gameguard (2).des, gameguard.des.
It worked for me
