Licence Problem

First of all sorry for my bad English.^^

My computer crashed yesterday and now the IT guys gave me a different machine.

But now the problem is that we only have this licence and i cant pull it away from this old installation cause it doesnt exist anymore.

What can i do to be able to get my licence back and activate this marvelous programm to be able to work?

Would be great to hear an answer.

Cheers

Marco
