I bought and installed this on my computer a couple of weeks ago. It completely crashed XP twice!! The only program I have installed that has managed to do this. On both occassions I was presented with a blue DOS screen telling me XP enncountered a problem with software. When I was returned to XP (eventually) graphics had been reduced to low resolution and 8 bit colour. After "uninstalling" the software and using system restore to the preinstallation point, I still encountered the same problem. It was only after looking through my registry and the rest of my system that I discovered it all littered with Acronis True Image entries, which I have now deleted manually. So far, so good, I hope I am rid of this dreadful program. I have sent Acronis an email requesting a full refund, but suprise, surprise haven't heard a thing.
