Scanwizard Pro Error

[buzfar]

Hello;

I have a G5
OSX 10.3.9
Scanmaker i900
Photoshop CS

I recently upgraded the os to 10.3.9, and since then I cannot use my scanner. I uninstalled the drivers for the scanmaker, and re-installed. I tried this for Scanwizard Pro 7, both 7.52 and 7.55. Neither worked, and when I used 7.55 Scanwizard would not even show up as an option with Photoshop when I used Import...
When I installed 7.52, scanwizard did show up in the import option on Photoshop, but when I selected Scanwizard, I would get the error "scanner driver not found". What?

Any idea how to resolve this? Right now I have a $500.00 paperweight on my desk that I would like to be able to use to scan!

Thanks
