Half-Life and Opposing Force Multiplayer

I've been using ogc for awhile in a variety of other mods, however, when I tried using it for HLDM and Op For, things didn't turn out too well.

When I use it for HLDM, the esp works fine and all, but the aimbot is a one-use thing. It'll aim automatically the first time around, but after that.... its up to skill and talent (=P)

As for Op For, the sucker crashes!!! I can't even get into a server with it. I've tried a few other cheats, but I'm new on the whole cheating scene so I don't really know my way around quite yet.

I'm looking for an aimbot. Wallhack/esp, doesn't really matter for me. Just an aimbot, nothin' fancy. I'd like it to work for Opposing Force as well, if anyone can help me, please do =x
