Can't deactivate Trados Studio 2014 Freelance Plus for moving to another computer (either with deactivation in software or via the offline option)

I have a licence for Trados Studio 2014 Freelance Plus, I want to shift the software to a new PC. However, the deactivate button in the software generates an error (Error 202: lock info is not matching) and the offline option in my RWS account also does not work (the deactivation code is not accepted). Can you please assist me?
