Can't deactivate license

I've been travelling and deactivated my TRADOS license to be able to activate it on the laptop I was going to buy. I did this, but the laptop broke down after just two days and I wasn't able to deactivate it before returning it to the store. Now I'm back at the office and need to activate the license on my desktop, but can't since it's still activated on the laptop that I returned to the store. Is there any way to deactivate my license so that I can get back to work?
