I cannot do a 3 PC install of NIS 11

I had to repartition and reinstall WinXP + Win 7, and reinstall NIS 11 on both. I can only reinstall NIS 11 on 1 of the operating systems on the dual OS PC.  (Previously was on all 3)

It lists on my NIS 11 cd up to 3 PC's, but when log on to Norton account only lists 2 PC'S only???

 

dual boot system + laptop
