Hi Andrii,

I have already explained in your previous post what needs to be done   https://community.rws.com/customers-partners/partner-groups/rws_campus/students/f/generic-questions/59133/problems-activating-my-trados-license 

Kindly inform your professor to remove/delete you entirely from Trados Team and then to add you again and send the invite. You are now an Inactive user, therefore you need to be added again and have the invite sent to you again. So please pass this to the professor, to remove you and then to add you again and invite you again, and please accept the invite when it is sent. But the professor needs to remove you first and then add you again and invite you. 

Good afternoon. Today, my professor sent me an invitation, but the error persists. What could be the issue?

Did he also delete/remove you from Trados Team you before sending the invite? It is important to do that first. 

I just had a chat with the teacher to learn more about this, and he said he had removed me and then added me back. When he added me back, anyone who had already been added would automatically receive an invitation to activate their account.

Ok, but when did he do that? Was it before the expiry of the invite? If yes, then he needs to do it again.

I will explain what happened more clearly. At the university, we were given new email addresses, which we then used to replace the previous ones in our RWS accounts. Our teacher added these new addresses, and we received invitations to them. On that day, I encountered an error and wrote to you about it for the first time. I attached screenshots showing exactly what the error was. You replied that the teacher had 48 hours to remove me, add me to Trados Team, and send an invitation. I accepted the invitation. However, within the next 48 hours, my teacher did not send me an invitation because he was having problems with his email. He eventually solved the problem, but by that time, quite a bit of time had passed. He sent me an invitation, but the error remained the same.

As for the license it was revoked due to the presence of new emails.
