Error when upgrading spreed from NC 12.0.5 to 13.0.0. - shared hosting

[DaCryptor]

Cannot upgrade to NC13.

NC-upgrade itself worked, but spreed won't update.

Error:

Doctrine\DBAL\Exception\UniqueConstraintViolationException: An exception occurred while executing 'INSERT INTO HhHvb_talk_rooms (name, token, type, password) VALUES(?, ?, ?, ?)' with params ["", "6634", 3, ""]: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '6634' for key 'tr_room_token'

What can I do to have this fixed? Already had spreed installed in NC 12.0.5

Please help.
