Have big issues today and calling on all ears since Tech support is closed. I have a HUGE file that keeps freezing which has forced me to force quite numerous times. I'm suspicious that its either too many cars or too many trees that is causing the slow down. But then came the mega issue. After one of the force quits I reopened the file, all the cars which were on a car layer and turned off, were on and on a different layer. then I realized all but 2 layers were all cleared out. No objects remained In the file. Everything but doors and cars were GONE! Not yet panicking because I had multiple back up files from earlier today, yesterday and earlier in the week. The Panic set in when each one of those back up files opened and only the cars and doors were there. no matter when the file was saved or at what stage, only the cars and doors are opening. It was bad enough that the client gave me 4 weeks worth of work to accomplish in 9 days. Now this! ANY ONE EVER HAVE THIS PROBLEM? ANYONE HAVE A SOLUTION?!? ASAP
