I have been using SpectraView for 2+ years with my NEC PA301W and LCD2690WUXi displays, no problems at all. Suddenly the calibration process won't complete for the PA301 – it gets to 38% (White Point) and sits there, apparently frozen, for 5-10 minutes. Then it gives me a generic error message. ends and tells me that the display is not calibrated. Other monitor is fine. I deleted the program and installed the latest version, same results. Any ideas?
