Game screen won't work

Hi, I have had the game for about 45 minutes on steam, when I quit to make a new game (so that I can start over without the tutorial) I went to settings first to see what all I could do there, I checked the mods area and clicked a button that would take me to the mod area on steam, when I tried to get back into the game (I never downloaded a mod) the screen turned white, then flashed black and white rapidly, then white again. I can hear game music and even click stuff but the screen is completely white. Help? (This is on steam, mac book pro)

I don’t know how to delete this topic, but apparently other people had my problem, I solved it using their thread. Thanks! :smiley:
