Edrawings 2013 crash

Since upgrading to edrawings 2013 we have been seeing a lot of crashes on anything over 5mb.  Anyone else seeing this, is there resolve for this?  Also the Document API manager is giving us grief.  Any drawing that I have a custom material called out on is displaying the path where the custom material is, but not the material.  So overall i'm very dissapointed in edrawing 2013.
