dunno what the deal is, but am stuck on this screen (i own the game) and wont let me log out either

If Steam is having issues it can affect your ability to log in, as it is no longer able to verify the fact you own the game. If this issue persists, please get in touch with our Support team directly!

You can do so here:

And we should be able to get you back in-game ASAP.
