I have a brand new HP PC running Vista SP1 64-bit. I have installed True Image 11 Home and every time I try to run a backup it completely hangs the PC (mouse unresponsive, can't start task manager etc). I can leave the PC for hours - but it stays locked up. Only a power cycle can restart it. I have downloaded the latest version of True Image 11 Home from the Acronis web site - uninstalled and re-installed True Image - but all to no avail. The backup location is a network drive mapped on an HP Media Vault on my wireless network. This works flawlessly on my XP PC running True Image 11. Ideas?
