All of sudden, SilverFast AI will only scan reflective materials on my Microtek. When I try to scan transparencies, I get an error message: "An error occurred at the start of the scanning process. Can't calibrate scanner." I thought maybe the calibration was the problem, so I tried to recalibrate with my Kodak IT8 target, but I got another error message: "Couldn't create the output file." I was successful at recalibrating with my reflective target, but I can't get the scanner to either scan a transparency or recalibrate using the IT8 tranny. Any ideas on how to solve this problem would be appreciated. (I did download the update of the software, in case there was a corruption issue, but still no luck.) Mike
