I have a problem when scanning with my Coolscan V. Everything seems to work well until it tries to perform the ROC and GEM features. This only happens at the actual scan and not during the preview phase. I get a warning that says, "There was an error in performing a post processing" It used to work fine before and the weirest thing is that the first scan after power the scanner on works well and at the second scan I get the warning. Is it a software or a hardware problem? I installed again the Nikon scan software and even updated to 4.0.2 version from the Nikon site. I recently updated to XP2 but as i said the weirest thing is that sometimes it works and sometimes not. If i do not get a clue here, I will have to call nikon support but then I will have to wait until monday. Thank you for your help.
