Design Review 2013 freezes or closes unexpectedly

[cwalls]

Having a problem with viewing a DWFx and DWF 3D file created in Revit Arch 2013.  After a few minutes of viewing and zooming the program will generally just close on its own or occasionally freeze.  The files are 9Mb for the DWFx and 6.5Mb for the DWF version.

Tried on multiple in-house computers all with same video card (nvidia quadro 2000) and 12Gb ram and same issue occurred.

Took file to school where I teach part-time with different video cards (ATI) and 12Gb ram with same issue.

I am concluding that it is not a video card issue (yes I did update my nvidia drivers try 2 different version with no luck).

Anyone else having a similar problem?

Thanks

Can you share one of these DWFs? www.wikisend.com is a good site to use to share large files, ther are others as well.
