NIS Security re-installation question

HI guys, I hope you can help me. 

 

I have installed NIS on three PCs which went fine. However yesterday I decided to upgrade one of the machines from Windows 7 to 8. Unfortunately I was experiencing all sorts of problems so had to refresh the PC. This has solved the problems but in the process it removes your programs and  it means that I have to reinstall NIS.

 

The only problem is that in my account it is telling me that I have no 'Available Installs'. How do I reactivate my Norton subsription on this PC?

 

Thank you in advance for your help.
