LEGO RIS 2.0 CD or LeJos Config Help

Hello All:

I brought Lego Mindstorm Kit RIS 2.0. Apparently during move I misplaced the CD.Now that I have a new PC, I was wondering if I could get the CD somewhere. In the meantime I was trying to use LeJos, but it fails to upload the firmware.

It gives me an error "Error:Opening \\.\legotower1".I did set all my environment variables right (I guess) Here is the snapshot of the env.

ProgramFiles=C:\Program Files PROMPT=$P$G RCXTTY=USB

Any help is highly appreciated.

thanks

Mohan
