Game will not launch

I have seen this issue across multiple sites, with no resolution.
I click 'play' and it shows me in the friends list playing Rising Storm: Vietnam but after 4 seconds it goes back to blue with no game being launched.

I do not have any folders in MyDocs>MyGames.
I have Win 64x.
I did receive a beta key from pcgamer a few weeks ago for a beta weekend. After the install for that beta weekend, the same issue occured.

Is there any known fix for this?
