Iam using a Scabber Pro S3 dual camera. Iam having issues with 5.5.1 while in the calibration process the calibration button is won't depress. I had 5.5.1 running yesterday. I did aNvidia driver update today and ran the scanner for 30 min then blue screened. I rebooted and tried to Calibrate and it would not. I rolled back the driver and that didn't help either. Iam dead in the water. Does anyone know it there is a video driver that I should use or anyone had this or similar problem?
