win2000 umax 2000 u scanner problem

im beginning to sound like a broken record to myself so I though I would ask the question. I have a dell xps running win 2000 and a umax 2000U scanner. I have downloaded the upgrades, updates, drivers, etc. I reinstalled vistascan software and reloaded the drivers. Im getting a 0000000h errror. Someones the test works and sometimes it dosent. the vista icon shows up in the lower right hand corner of the screen but when right clicked on and when I choose turn light off it dosent go off. SO i rebooted and now there is no little icon on the screen and now when i wanted to do a test scan i get the error message 0000000h. Any ideas?

 

Maybe you can find out something here .

 

thanks for the link. ive been trough it, i should have mentioned it in my post.
