Passolo license transfer

I own Passolo 2011 and I need to transfer it to a new computer. In SDL account > Products & Plans > Licenses, my license shows up as in use, however the computer it is on is not accessible because it is broken. On the same screen, I get the link "Can't deactivate online? - Deactivate offline" (there is no other link). That link wants me to enter a deactivation certificate that I am supposed to find it inside Passolo.

Does anyone know how to transfer a license to another computer when one has no access to the computer on which Passolo is currently installed?
