Something had to change, we just can't figure out what. Did this problem happen to all of us at around the same time (The last couple of days) or is anyone else having it for longer?
Something changed for sure. Now, where?
Re-installing didn't work for any of us, so it shoudln't be anything associated with the game files, right?
Re-booting worked for some of us, for some time, and that makes me think 'Windows'.
