canon DR 3080C-II when trying to scan from within an application scanner reports it is locked

[rew]

when a my computer & scanner was moved the scanner stopped working.  It is reporting locked by another application.  It did work a couple of times the first day.   It has been uninstalled and reinstalled both software (driver)  and physically and the computer has been rebooted (cold and warm) several times.  I have also replace the USB cable.

Hi, rew!

So that the Community can help you better, we will need to know exactly which operating system is running on your computer. That, and any other details you'd like to give will help the Community better understand your issue!

Thanks and have a great day!

I am running Windows7 Enterprise and using the USB  connection on the scanner.  II can't get the scan panel to use the scanner either. This scanner has been connected to 2 other computers and has performed fine until now.
