epson scanner with OS 10.8

Finally upgraded to OS 10.8.2 from 10.6.8. Epson Expression 1640XL worked fine before, software was supposedly compatible. Not so. Image Capture does not control scanner either, even tho' that is what Epson say to use. Any suggestions on how to get the Mac OS to drive the scanner? The MacPro sees it and can start it, but it does not finish a preview scan. Yes, there are other packages to buy and Hanrick's works (the scanner and connection are fine) but who wants to buy more software?
