No cd-patches....more commonly known as 'cracks'.....are a means of bypassing using the disc the game came on. Technically, it's illegal and results in piracy. If you're using it, suggest you don't post it here.
To the OP:
Bottom line is, nobody here will be able to help you, irrespective of how genuine your case may be. It's against the forum rules. You'll just have to buy another copy of the game....or figure it out on your own.
Sorry bud!
