Use the Registry Checker program as suggested.
If you still have trouble, uninstall our software using the Nero Clean Tool. This removes most registry changes created by our software.
If that still fails to resolve your issue, then use a free registry cleaner, which you can find by going to www.google.com
and searching for registry cleaners, to remove any possible remanents of our software. And if you still have issues, then the problem lies elsewhere, and not with our software.
