Vista - Offline files is not enabled

I'm hoping somebody can help me here, I have been through every forum trying to find a fix for this problem and it seems a lot of people are having it, but other than the regedit fix nothing is working other than a rebuild.

My problem:

• I was using offlines on a share from a machine called \\Dellp4\share1, this machine went dead and another was builded but named \\server\share1
• My machine XPSnotebook still saw the old share and would not let me delete it, so I tried the egedit thing discussed by some as:
  REG ADD HKLM\System\CurrentControlSet\Services\CSC\Parameters" /v FormatDatabase /t REG_DWORD /d 1 /f
• This seemed to clear my dtabase but now I can not right click on the network and choose make available offline, it's just not in the menu
• When I go to offline files it says 'Offlines files is enabled but not yet active. restart the computer to activate the computer.'
• I restart the computer, but still nothing, I restart again, I disabled offline files, restart, and then enable. Nothing
• Other computers on the network can make the files available offline, just not mine computer.

Does anyone know how resolve this or how to re-install offline files

Cheers in advance
