Hp scanner won't work on vista

I just bought the HP photosmart C5280 All in one printer and it works great
except for printing documents using the software that came with the printer.
I don't think the software is defective because I installed it on my XP
computer so see what would happen and it works fine but when I try and scan
a document on my Vista computer, I get a Windows error message saying
hpqsnvw has stopped working.
Then more errors saying unable to communicate with HP scanning software,
verify that it's working and installed correctly.
And another error saying error occurred communicating with scanning device.

I did an online chat with someone from HP last night and they had me try all
sorts of things including running a diagnostic test that came back showing
no problems.
The HP tech told me to reboot my computer and then try scanning again
because she figured everything should be fine but it wasn't.
I had to go out last night so I couldn't try and reconnect with a tech and
before I do, I thought I'd see if anyone here has any suggestions.
I tried two different usb ports. One was a usb hub and the other was a port
on the back of my computer. Both give me the same errors.
I can bring up the Windows Paint program and scan using that but it doesn't
seem as if I can use any other software for scanning.
I tried using Microsoft document scanning but that too won't work. However,
it gives me a different error message. It says server busy. Can't scan
because something else is using the server. It gives me an option to "switch
to" and this brings up my start menu.
I don't know what it wants me to do or why I can't scan documents.
