problems with starting RO

[MachineHead]

Hello,

I have recently installed Red Orchestra, but as soon as I try to start the game via Steam a pop up appears telling me that Steam is checking the data of the game. The problem is that it doesnt even start checking/loading. Nothing is happening, no matter how long I wait.

How can I solve this problem?

I've already tried reinstalling steam and RO, deleting the clientregistry.blob and installing new drivers...

Ah, but did you verify the "game cache".

I think verifying the game cache is my problem.

Doesn't anybody know a solution for my problem?

I contacted the steam support, but didn't receive any reaction until now...
