UMAX Powerlook 11 scanner wont work with win2000

Hi guys.. i downloaded a new driver for my Umax powelook 11 scanner. I have the scsi card installed right but win 2000 keeps requesting a file scsimap.sys upon discovering the new device after rebooting. this file cannot be found in the driver files i installed. I was forced to download the file on the web and point the system to it when it requests the file. However all i get is the blue screen physical memory dump error.

please what can i do to install this right??
HELP!!!!!!!
