Major Error With Combat Arms

It says "The Program is running in compatibility mode"
"The Program is shutting down" and this happened after i downloaded Iwin's bypass. then i replced it with the other 1. Then i wanted to play some combat arms and i replaced his bypass with the REAL ENGINE and it did the same thing. "The Program is running in compatibility mode"
"The Program is shutting down".

Try re-setting it up again? or perhaps re-download.

Try Un-installing your CA, then run setup and re-install it. And also depedns on which PC your using, Vista or XP? This is main part.

delete combatarms and files of combatarms than re-install... see if that works.

That's exactly what I said, but deleting CA files won't work you have to actually un-install the game.

A great fix.
Use the launcher.

It happened to me before, and using the launcher is how I fixed it.
