I was able to play the game with no problems at all. I stopped playing for a bit and yesterday I go to play and I get the message: The instruction at "0x636ec8ec" referenced mem at "0x636ec8ec". The memory could not be read. Click OK to terminate or Click cancel to Debug. I have no idea what is going on??? There have been no major changes to my pc. I have already uninstalled and re-installed and still nothing?
