Thanks for the headsup Tommiy2.
I wasn't as lucky as you however. I had to try 15 times before it accepted my registration.
5 wasted days, and many hours of reloading software, resetting settings that were never necessary.
Only thing that remains now is an apology and explanation from mcafee for this screw up.
Now to try the other 3 pc's and see if they work....but first a small drink to celebrate.:D
