I run windows 7 64 bit.

It was working fine until i made a change to make hidden files and folders seen. After that the game stopped working. Then i tried tweaking administration access and think i made things worse. Now am at a loss as what to do at this point. Can anyone help please.

Also, here are my system specs in case they are needed....
