Game was working perfectly fine till the last update. Now I cannot open the game. It stays stuck loading, and even on the very rare occasion that the game does get passed the loading and goes into "Checking for game add-ons" it gets stuck there and I cannot continue. I've left it running for 20+ minutes and nothing. Very frustrating as this is my weekend gaming away form med school and I can't play this game with 43 hours in. I have tried checking but I cannot find information to help me. Anyone have this issue or know a solution?
