[Failed to contact key server- help]

I just purchased Arma 2 CO, downloaded both games over night.

Arma 2 works just fine, but every time i try to start operation arrowhead or combined operations it says that there is no connection to the key server.

I found only the problem but no solution to this.

(i know i'm resurrecting an old thread)

Thanks, anchuin
