==========================================
if you want to login in mpgh use ur mpgh username and password
if you want to login in combat arms use ur combat arms ID and Password

Considering you said you tried your MPGH login, they must be VIP's. Which I know nothing about but Im sure Dave spent hours on a thread somewhere to prevent questions like these. It might even be called VIP SUPPORT at the top of this very page.
