Cannot activate SDL Studio 2014 licence on second computer

Hello,

After a laptop crash I reinstalled SDL 2014 on my laptop after doing a forced return. When I try to activate the licence, I get the message (in French, sorry): La licence ne prend pas en charge  SDL Studio 2014". I have SDL Studio 2014 plus and before the crash I was using the licence on 2 computers.

Thanks in advance

Martha
