Revit mep: Export to dwg fatal error. Sync fatal error as well

Has anyone else had fatal error when exporting to dwg format with Revit mep 2012?
It's happened 3 time's in the last hour for me. I installed the revit service packs when i got this new computer 2 weeks ago, and everything is up to date.

Our Revit master is busy at the moment and i wonder if anyone on augi has a fix.

I had fatal errors when i sync'd a week or so and i think he deleted the error message on the revit server and that cleared that issue up. Any ideasa from my augi brothers?

AUDIT the model??

I've got all the updates and service packs, turned graphics exel off 2 wks ago. I've audited the file no better today. hmmmmmm.

Same issue here any solutions?

Would it be possible to send me a copy of the project(s), and the steps needed to see the problem you encounter during export to DWG?
Any project files you provide data will be kept confidential and only used to research this problem.

Usually when I see this it's a problem with the network - the connection is briefly lost for whatever reason and the save operation is interrupted. Try exporting to a different network location or your C: drive.
