problem with license activation on reinstall

Can anyone give me some advice on this? I had a PC crash and am using a new PC. Windows 7 64 bit. I already had cubase 6.5 and was running that on my old PC. I have reinstalled Cubase 6 and it is running fine. I have my old elisenser plugged into my new PC. Cubase 6 installed with not problem. When I downloaded the upgrade to run 6.5 it is not reconizing my license and will not open 6.5. Can someone give me an answer on this? Thanks!!!

Install the latest e-Licenser software.
