Have you updated your lightpack firmware? Current Version is 7.5

If you haven't, the current version and a tutorial can be found at the bottom 
of the linked page.

Yes I've updated the firmware.  I've disabled Windows Aero and remove the
Logitech mouse.  I attempted removing and reinstalling the prismatic
software, but the uninstall software doesn't work anymore

I am getting the same verbose error as others have.  The lightpack is 
recognized in windows, but prismatik says in the configuration screen, at the 
top under firmware, "read device fail".  I read in another issue that a person 
went back to version 6.2 of the firmware and got prismatic to work.  Where can 
I get version 6.2 of the firmware?
