Beta Download - Eastern Front factions don't work

I downloaded the beta for the new steam version of Company of Heroes a couple days ago, as I couldn't play online opponents anymore.  Since then, I can't select the Soviets or Ostheer in Eastern Front.  Any thoughts?

It's bugged do not use the beta. Just switch back to the normal CoH and it well auto revert to the  version. We are trying to get in touch with relic about the issue and will fix it hopefully before they push the full version.

Can you tell me how to switch back to other COH as you mentioned in your reply?  Will this enable EF once again?

Thanks!

That answer was for the guy who asked in December 5th, we are far from that date and the update is mandatory, so there is no way you can roll it back atm.

Thanks BB, I was afraid that you were going to say that.
