I am currently running SolidWorks 2007 and am trying to open some assemblies I created in SolidWorks 2004. The previews of the assemblies look correct but when I open them almost all of the parts lose their appearances (turn grey) and most of the mates go bad. I was wondering if there is something I need to do to these older files before I open them to ensure they work correctly.
Sorry I had a typo, I am currently running SolidWorks 2009 not SolidWorks 2007.
