Plotdlg.ma can't be loaded

Hi All

OpenBuildings Designer Connect edition 8, version 10.08.00.44

I've got a user who is getting the error message that the plotdlg.ma cant be loaded.  He can load other .ma files without any issues.

It's a network build that is working for everyone else. 

We've deleted his preference files

The .ma file is in the path of config MS_MDL

We've replace the Plotdlg.ma with one from a working computer.

Is there anything else we can try before doing a full reinstall?
