I just downloaded and installed the 2009 pre release and Iopened an assembly that I have been working on for a few days in2008. The assembly has some errors, some of which are easy fixes,but one has to do with two mounting bosses that fail. I can't getthem to work at all, and I had no problem creating them originallyin 2008. I haven't saved the file and have tried opening in 2008and I don't have any errors, but every time in 2009 I do. Is thereanyway around this, I'd like to be able to use 2009, but if I can'treliably bring in previous version's files I don't think Ican.SolidworksGeneral
