Have you already tried the online activation? If you have access to the PC, this can be done from the Trados software, Help - Product activation.
If you do not have access to your PC, please reset from your RWS account, Products and Plans - Licenses: https://oos.sdl.com/asp/products/ssl/account/mylicenses/licenses.aspx
The full procedure is described at this link: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0038545
Please wait 30 minutes before reactivating. The activation procedure is described in this article: 05.4 Activating the Trados software after downloading and installing
