Hello, I use solidworks at work and I have a copy at home to learn API programming. Of course the one at home has been cracked. I work under windows XP and whenever I rebuild a drawing (never a part or an assembly) Solidworks crashes. This behavior started from the 2004 release and it happens on other two computers I have tried. Of course, being the program cracked, I can't use the service packs. Does anyone have an idea about it? Do you have crack that allows me to install the service packs? Thank you for any help Jacopo
