I have a CanoScan LiDE 210 that I've been using for the last two years at least.  I recently used it about a week ago and had no issues with it.  For some reason when I tried using it today through MP Navigator and Solution Menu it doesn't work.  I get an error from Solution Menu where only the help features are available to be clicked and from MP Navigator it tells me that it cannot start.

I have tried reinstallation and even the driver update available from your site.  I'm not sure what the issue coudl be anymore.  I know it can start and the bulb works fine because when I plut the usb in my computer recognizes it and for a short while the scanner will light up, but that is all.  

I'd appreciate any and all help.
