NIS 2012 will not allow installing for the 3rd time

Hi all,

I have a windows 7 PC and recently had to reset it to factory settings which of course reset the trial version of the NIS that was on there.

There trial is soon to expire so I was trying to re-install my copy of NIS 2012 that I have installed twice before (it allows 3 installs) but it says the product key has expired.

I have signed onto my account and it shows that I have installed it 2 out of 3 times, so I should be able to install it again.

Any help or advice you can give.

Much appreciated.
