When configuring the Language Weaver Cloud machine translation plug-in, an error is thrown, with the message:

Your RWS ID account is not linked to any RWS Language Cloud account. Create an account or contact your RWS Language Cloud account administrator

It is possible to log into and translate via Language Weaver Online.

Access the Cloud in the browser. If you are presented with a Registration screen, asking for user details, complete the form and submit the update. The plugin should then allow you to configure it with the same credentials.

While your RWS User ID has been created, it has not yet been registered in RWS Language Cloud.
