i am having this problem also, exept i am on a mac.the error specifically is : "could not load main config file: config/default_main_settings.cfg", i bought amnesia through steam and just finished verifying the integrity of the cache with steam and it 100% completed updating the files and didnt seem to do anything as i still get the same error when i try to launch (the fragmentation is %0 also). i am so very close to the end and needed to check a guide so i quit the game and when tried to re openit it came up with this error, PLEASE HELP!!! I WILL BE ETERNALLY GRATEFUL, i am dying to see the climax of this game =[
