Activation lost despite no hardware was changed on my computer

 

I recently reinstalled Windows 7 on my laptop and lost 1 activation despite no hardware change.

The EA refused to work after re-installation and when I updated to 8.3 I lost one more activation.

What should I do?

Usually Metaquotes credits one activation for known major Windows updates, but this was done by you.
