Problems Opening Drawings in eDrawings 2008

I am having troubles opening some drawings ineDrawings2008.  It will open most fine but others it won'tfreezeeDrawings up.  It is not limited to only SolidWorks 2007oronly 2008 files, it is a mix.  I am wondering if anyoneelsehas had this problem and if anyone knows of something Iammissing.  It happens on multiple computers so I amguessingthere is something with the file but do not knowwhat.  Thedrawings open fine in SolidWorks also.
