Can't play Nomad Campain any more

As written I start play Nomad campain, but just few days later, the game stuck in the lobby where I select the nomad Map/campain. Pratically OK and Cancel buttons don't work, so I have to quit the game with ATL+F4.
I try to reinstall, but no luck at all.
Any suggestion?
