Wokka, please find here a couple of ideas that might help:
- restart the BIM Server or the computer that runs the BIM Server to restart the Messaging Server service of the BIM Server.
- Go offline on the ArchiCAD side and then go back online: Open the Teamwork palette and click on the arrow next to online, select work offline, then a couple of seconds later check it out to go back online.
Let me know the results of these.
