Epson CX7800 Scanner-All In One

I have a Epson CX7800 all in one and when I originally got my new
> computer, HP1730n w/Vista I had trouble installing due to compatibility.
> I can't remember what I did (I think install drivers from Epson) but
> both the scanner and printer worked for the last few months. Now all of
> a sudden the scanner is not working , error reads:Epson scanner cannot
> be started.' When I right click on Epson settings it reads under scanner
> status: Scanner is not ready. Interface: Not Connected Option:Unknown.
> I've checked and checked connections, wrote Epson and uninstalled and
> installed three times the new drivers, all times it says that driver installed
> correctly. Printer works just fine and I can copy. I installed just the way I was told.
> I don't know how it can happen when nothings changed. Can updates cause
> a problem? I'm not exactly sure what Interface means in that error msg.
> I feel I'm banging my head against the same wall. Any other options out
> there would be appreciated. Thanks
