Problem with FF7 patch(no-cd)

[voronwe]

Hey there, i got a Patch(No-Cd Crack) for my FF7 from megagames.com (it's called FF7Riva.zip).
When i use the the "Patch.com" it says:

Opening File : [ ff7.exe ]
Searching Progress: .....

Error: bytes not found
closing file

press a key to exit

And it creates "*.p" filetypes into my FinalFantasy folder.

If i try to start the game, there pops up a blackscreen (no message like "insert cd1 ...") and then it throws me back to my desktop.
Any hints or solutions where the problem could be?

Thanks for reading and think of possible solutions

edit: allready tried "refreshlock"
