I have the same problem.
Every couple of weeks I do a full system backup. No problems until today.
Hre's what happened - I couldn't get Backup to run. No way, no now. (I"m not talking about restore points, I'm talking about a real full backup).
What's changed since the last backup?
All I can think of is that last night I got the update notification from Microsoft, along with an invitation to install Microsoft Silverlight. I did that and it appeared to install successfully. (It doesn't appear on my desktops "All programs" listing, but as a tool it might not belong there anyway).
I even tried running "NTBackup.exe" from the command line... and again, nothing happened.
So... what happened and more importanly, what can I do to fix it?
Thanks for any assistance or ideas you can provide.
