So for just about every hack I have tried for COD4, with the exception of 2 that were for version 1.5[one of which didn't work very well] have all given me an error when I try to run them. I get a Windows message saying "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.". I am on the administrators account, I turned off my anti-virus and then made the hacks a exception on the firewall, I made sure correct permissions were given under properties and security. I have run out of ideas, someone help? I have seen other people with this problem, it sounds like its not very uncommon.
