Query: Problems with Windows 2000!!!

Having used Powerquest products before, I thought this would be great. However, I have tried it on 2 Windows 2000 machines with near disasterous results. I couldn't even get it to install on the first machine. The second machine installed it ok, but when I tried to create a backup, it got about 1 minute into the process and shut my machine down - BOOM! - no shut down proceedure, nothing. It was as if I had hit the restart button. I don't have to tell you how dangerous this is to an operating system; could have wiped it out, ruined the registry, etc. Fortunatly, no permanent damage was done. However, I guarantee you I won't be trying it again. I'm sending this back for a refund!
