Scanner Help

I have not used my scanner in a while and when I tried to use it today it didn't work.

Here is what I had to last time:

When I run this: cd ~; wget http://people.freenet.de/go-mcpop/cism216.fw; sudo mv ./cism216.fw /usr/share/sane/gt68xx/

This is what I get: metungkp@MetungKP:~$ cd ~; wget http://people.freenet.de/go-mcpop/cism216.fw; sudo mv ./cism216.fw /usr/share/sane/gt68xx/

mv: cannot stat `./cism216.fw': No such file or directory

I found this and did it and still it did not help:

I just want to make sure I did this correctly:
##############################################################################
cism216.fw sudo cp / usr/share/sane/gt68xx /
usb 0x07b3 0x045f
override "plustek-opticslim-m12"
firmware "/usr/share/sane/gt68xx/cism216.fw"

Please help...
