HiNils Eftring 

Before activating the program on a new PC, a license reset must first be completed.

In case your computer crashed, or you can no longer access Trados from your old computer, please reset your license from your RWS account – Products&Plans - Licenses&Subscriptions as indicated in the article below:

Please note you need to wait 30 minutes before you can activate on your new PC. The license code is located on your RWS account--> Products&Plans--> Licenses tab: RWS Account

If you no longer can reset the license by yourself, please let me know and I will raise a ticket for you. 

Thank you. I am for the moment very busy so I will try your recommendations within the next days.
