Query: Major Problems with Registry Repair & Stompsoft Corp

I purchased Registry Repair and followed its installation instructions the same day only to have it create a registry error that Windows had to fix. When I attempted to delete it, the progam was already gone but a message remained stating that my 15 day free trial period was past - the program deleting itself. Tried to contact Stompsoft via its online site but it would not accept complaint messages; tried calling their non-toll free customer support line, but got frustrated with the looong holding time; sent Stompsoft's president a certified, return receipt letter, but he has not accepted it. Draw your own conclusions about Registry Repair and Stompsoft.
