Deactivation failed

I have a problem moving on to using Trados Studio (2014 freelancer) on a new computer.
 
I tried to follow the instructions on moving the licence to another computer by first deactivating the software on the old computer, but this is the error message I received: Deactivation failed. Cannot deactivate license. - The computer no longer matches the information stored with the license. This may be caused by a cloned system.
 
I have been using the software on this computer since the beginning, and I DO have a valid license. All I can think of as a potential cause is that in November the hard disk failed, and it had to be replaced with another one. In the rescue operation they managed to save all the data to an image file, which was then restored on the new physical hard drive, and I was able to continue my work as if nothing had happened.
 
Now I have a new computer waiting so that I could continue working with Trados on that computer. Can you help me resolve the issue?
 
Best regards,
