EA activation used on already activated computer

 

So an EA I had already activated on my laptop ended up using another activation when I went to install it on a different terminal on the same laptop, as I only had 3 activation's left this is kind of frustrating to say the least.

It's supposed to be one activation per machine right?

Anyone know why this would of happened and if there's a chance i can recoup this activation?

Thanks

 

Yes, it is one activation per machine.
But one activation may be lost because of Windows key updated.
