Once upon a time I installed a file shredding software onto windows server. This software was only the trial version so after about 30 days it expired.
Couple months later I decided to get the full version and tried to install it on the same machine (after uninstalling the trial version).
The problem is, after the installation runs I try to run the software and it says "Demo/Trial version expired" and I can't use my software.

I've tried a few registry cleaners and even went into the registry myself and searched for anything that possibly could be related to this application. Granted I don't know too much about where certain registry entrys are made upon installation I still feel I got most/all of it. Any suggestions on how to get rid of this trial version?
Thanks guys.
