Same thing was happening to me. I would load my file and about 14% I would get a eprom error and the scanner would reset. I load it a second time and it worked like a champ. Someone suggested I get the latest version. I was using 1.98 when this was happening. I installed 1.99 but haven't tested it yet to see if the problem was fixed.
