If the Windows Update killed your ability to use the Altronics software you don't have many pretty options. Microsoft won't let you "downgrade" back to where it worked. You could find a used laptop running a version of Windows that works and turn off Auto Updates. Then use this as your track computer. The other is to fork over the $100 for the Altronics update. Either way, when you get things working get a backup drive and make a full copy of your laptop every week. That way if it freaks like this again, you have a working duplicate on a spare hard drive that can be changed out for the one in your laptop with a screwdriver.
