I have a studio 1555 laptop two months old, after upgrading my system from Vista to Windows 7, Dell datasafe local back up software stoped working , the program keeps luanching by itself and gives an error mesasage constantly nonstop.

Also I can no longer see the second partition where datasafe stores the backup (D: drive) after upgrading the BIOS from A6 to A7 as it was recommended by dell.
