My company has a license to CosmosWorks 2007 Professional.  They are not going to upgrade any time soon even though we use Solidworks 2010 64bit day to day.  Solidworks 2007 sp0 keeps crashing on me.  I would like to find old service packs that will allow me to upgrade SoldWorks 2007 64 bit sp0 to any greater service pack, sp1, sp2, sp3, sp4, or sp5 (preferable sp5).  Any suggestions on where to find service packs, or how to obtain them from solidworks, etc.?
