error DAO.Recordset [3197]

[michielper]

I am getting an error that I have not seen before when saving a model and also when exporting a package:

DAO.Recordset [3197]
The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
-------------------------
I am using a local EAP file! No-one else is using it and I have only one instance of Sparx EA open..... So what causes this error and how do I resolve it?
Sparx EA version 12.0.1215

Try a repair with Project Integrity check. Eventually you can try a transfer to another EAP. Maybe you have a dead EAP in the background (reboot helps).
