PaperPort error with Visioneer XP200 portable scanner

The Visioneer XP200 scanner had been installed and used without incident.  Then all of the files in the user's temp folder were deleted (that's another story).  Since then when a document is scanned, it appears to be scanning OK but then it will stop short of opening PaperPort with an error message.  The message is entitled "Image File Error", it says, "Error in image file reading and writing software. (Error No. -10)" (I don't know if these two events are connected or coincidental).  You can click OK and PaperPort will open but the scanned document doesn't appear.  At first, I tried a System restore to the day before.  It didn't make any difference.
I called Visioneer techinical support.  They said unstall PaperPort and the scanner driver.  Run the ScannerSW_Uninstall utility.  Then reinstall PaperPort and the scanner driver.  I did.  I still have the error message.  I noticed on other notebooks that have XP200 scanners installed that there is a folder named OneTouch in the Temp folder.  Support told me was normal but there were no other folders in Temp that affected the scanner.  That folder reappeared when I had reinstalled the software.
I called support again this week and told them what I had done and that the error message remained.  I was told that "they had remembered something about this error message but couldn't remember what had been done about it". I found that rather disconcerting.  They said they would get back with me on it.

Has anyone had to deal with this error message and if so did you find a resolution?
Thanks,
Ted
