I doubt that your computer is the issue. Did you extract it to a really long folder path, by any chance? I found this suggestion from somebody else having the same error:
"I discovered another cause of this problem and solution. If your game is zipped and you extract it to a folder that is too long -- but still unzips fine -- this error can pop up. I believe it's due to the game accessing the data folder and mono.dll within its sub-folders... and somehow this access cannot be too deep in the directory structure. Move the game to a less long folder and it will work -- IF this was your problem in the first place."
