Thanks to all for comments and suggestions. I went looking for a TWAIN driver and found the following comment:

Cons: Note that this scanner only has a TWAIN driver available. Photoshop CS4 does *not support* TWAIN drivers on any 64-bit operating system. So if you have 64-bit Windows 7, don't fire up Photoshop CS4 and expect to see an "Import > Scanner" option. You have to run the scanner from a separate application, save then scan, then import the result into Photoshop.

I am running Windows XP and the scanner came bundled with Adobe Photoshop Elements and ArcSoft Photo Studio. So far the only TWAIN downloads I have found are through DriverWhiz, Driver Cure, and other such programs that promise to scan my computer for missing drives, etc. with a cost of $19.95 and up. I do not mind paying for something that is going to work and provide what I need. But I just got the computer back after a virus attack and I am a bit jumpy.
