Howdy, Finally got my key and finished my day's work! But now that I launched/patched the game, I'm signed in, see my username. But all the options are great out except for sign-out and exit. Other than that I can watch the alpha intro video, but that's it.
It's a temporary issue (as in, as far as I can tell, it lasted for all of fifteen minutes). Load the launcher, click "Verify files" and patch to 49167, the current version. Then everything should be peachy (as an alpha gets).
Please get patched to 49167. Report back if you still can't access any ubernet or quickmatch game modes.
