Ravaged Beta Problem.

Maybe updating, servers are down for maintance or offline.

Restart steam

If this does not work: verify integrity of game cache

if this does not work then: delete and reinstall

if this does not work u have to wait

Usually step1 or 2 always work....I would wait a bit,too,before I try step 3. Dogfighters was once unavailable for 2 days and it was not the problem of the client
