The reinstallation of Windows makes it look like you installed on another machine, thus the activation.
Only the Service Desk can possibly help you.

I reinstall window and reinstall everything including MT4 and EA i purchased on the same PC.
I lost 1 activation after that. Is it possible to regain my lost activation?
The EA i purchased cost a couple thousand dollar. it would be a huge cost if i lost that 1 activation.
