Epson scanner wasn't working today. I unistalled it and reinstalled it. That didn't work so I unplugged power and USB cord to scanner, then restarted computer, then plugged in the power and USB cord again. By doing that the drivers were reinstalled. Now the scanner works again. Images are fine except the scan to email doesn't work. When I click scan to email button I get "%s Application can't be found."

Does anyone out there in syber space know what's going on here? I could sure use the help. Shade Tree can usually fix anything.
