What you could try is to run the pc client again (or any other device) in case it still has your data
Run that client without a connection to the internet!
Now drag & drop all your favorites, identities etc. to the local area (can also be done via right-click on items).
Now connect to the internet again and login with your new password or do the fallback.
Now you can put them back into synchronized area.
This time make sure you have stored your recovery key! You can generate a new one under settings - options - myTeamSpeak
