/Moved to general.

Don't use a hack?

no i dont use any hacks at the moment and its still now working?

Same problem. It goes though the now loading screen, then closes out, and shows the ending banner..

No hacks, and I noticed Hacksheild took longer to open the first time this happened.

No De-bugs in the Combat Arms folder either...

Suggestions and tips would be nice.
