Total LV Fail

[cirrusio]

Has anyone else seen something similar to this? I have a large project that I am working in.  I save each file as I am going and immediately before I shut LV down.  LV appears to shutdown properly (i.e. no complaints), but when I open it I get the file recovery screen with a lot of VIs I was working on previously working on.  And as it turns out, many of the changes that I am 100% certain I saved in the previous session are not saved (i.e. they look like they did prior to saving).  I haven't tried hard to reproduce this, but this has now happened a couple of times and I am not sure what is going on.  I am running LV 2010f.2 on 32-bit Windows 7 Enterprise.

Thanks, Matt

I once had a similar problem. It was also a larger Project File ~ 80VIs (LV2009SP1, WinXP). I solved it by saving the whole project for a previous Version of Labview (was possible in this case) and to another destination on my HD and since then it worked properly again. I lost one day and a half of work before I got what was going on.
