White Screen of Death?

[diarmaede]

When I closed a VI on Monday, everything was working fine.  Now, when I try to open it, I see a white window, with only the green checkmark and the "0" from the error box showing as I try to load the VI.  Eventually, I see a "(Not Responding)" message in the title bar of the VI.  I have stopped trying to load and then tried to load the VI several times with the same result, waiting up to 20 minutes to see if anything happens.

Of course, like an idiot, I have not made any backup copies of this VI in a week or so, so if I cannot get this to run, I am kind of screwed.  It is a relatively simple VI that connects to a USB-6009 and reads 5 single-ended AI inputs, then parses and logs the data.

Does anyone have any ideas as to how I could make this thing load?  Any other ideas on what I can do if the code has somehow become corrupted?

Thanks.

If you post your VI (you probably have to zip it or something since the website is much better at blocking VI attachments than callgirl spam) I can try out a few things on it.  Sometimes it is as simple as trying to load in a different version other times I have to reach into my bag of tricks.

I wish I could, but company policy prohibits my posting the VI.  Sorry.

No need to be sorry, not my code that is lost....

OK, now this is interesting.  If I save the VI in a project, I can open and run it from the project window, but if I save it after I open it, then try to open the VI I just saved normally, I get the same white screen.

Of course, I try the simple stuff last.  I shut down the computer, turned it back on, and everything worked perfectly.  Thanks for your help.
