Problems with Epson 1200s and XP

[Thor]

I’ve just installed a scsi card for my new scanner. I’ve also had to update PhotoDeluxe Home Edition 3 with the EPS Parser plug-in that is needed for XP.

The card is an Adaptec AIC-7850 PCI SCSI contoller

When I try and scan I get the following:-

“Could not open the TWAIN source. Make sure there is a valid source for your scanner in the Twain directory found in Windows directory”.

I’ve now tried every download/update and service pack that’s going.

I still get the same error message:-

Rather new to computers so any help (and in idiot proof language please) would be very much appreciated

Cheers
