After many hours of downloading, I was finally greeted with this message... [URL]http://www.mikejwilson.com/misc/total_lameness.jpg[/URL] SolidWorks actually changed the file as I was half-way through downloading it. Now we have 2.1 OLD and 2.1 NEW. So if anyone is on dial-up trying to get this latest Service Pack, don't be surprised if your file fails. Does anyone else think SW should have changed the rev to 2.2? I know this is a bizarre case, but yet it happened didn't it? I guess it's damned if you doo situation. Mike Wilson
