Could one of your subVI's being causing the crash?
I was able to open the VI just fine in 10.0f2, but I had to tell it to ignore the half dozen or so missing subVI's.
I'm running labVIEW 10.0 Development system.
I just get a white faded out window with a prompt to close labview when I try to open the vi...
Would it help to upload the vi's that i call from the top-level vi?
If that's what's really causing the crash, then yes, it would help.
You may also wish to update your LabVIEW, since there has been a patch released for LabVIEW 10.
Sub vi's called from top-level vi attached below.
I'd be grateful if you could have a look when you've time.
