Adobe Photop - Registration screen keeps popping up

So you've registered your Photoshop and it's asking you to register again and again?
Well it's an easy fix, the problem we've got is with CS2, it may work for other versions.

- Make sure Photoshop is closed.
- Navigate to your installation directory.
- Delete/Rename regsresen_US.dll.

See screenshots below. Goodluck ;)
