Reinstall after crash

My operating ssytem crashed. I had to reinstall  the recovery program. I had a Norton Antivirus 2011 good until Oct 2011 but it wont let me put it back on the computer that it was on that I needed to recover  saying all downloads were used which they were.. The computer works fine now but I have 9 months left on my subsrciption that Norton wont honor. When I called Norton they tried to sell Me $399.00 of tuneup software!

 

Any  help out there?

 

Thanks
