Hi there, not sure how the license got activated to begin with, but the reset information is exactly what I need. Thank you so very much for your help!
I have been able to track your account and can see you purchased SDL Trados Studio 2015 back in April 2015 which indeed entitled you to 2015 free of charge upon release.
Our records indicate that you also activated the license on your PC on the 5th August 2015-
To activate a license, it is necessary to access your SDL account and then copy and paste the activation code when prompted (after Starting Studio)in to the activation box.
You can of course request a license reset at http://support.xl8.one
Our licensing team will then invalidate the original license activation and reset this for you.
