VI will not open; tries to open itself as a sub-vi

[nislyj]

Hello everyone, this is my first post here as a relatively new labview user.  I have a problem that I was hoping someone could help me out with. 

I have a vi that worked fine yesterday, but will not open today even though I made no edits to the file between today and yesterday.

For the sake of conversation, my vi is called TC.vi.  If I try to open TC.vi, the dialog that usually pops up when it can't find a sub-vi pops up and asked me to locate TC.vi.  If I open TC.vi from this dialog, the dialog pops back up immediately.  If I cancel, and click on "ignore sub-vi" the VI stops loading completely. 

I have tried now on two different PC's with both v7.1 and v7.0 (the vi is a 7.0 file) and have tried re-naming the vi to something else.  Whatever I name it, that's what it asked me to locate when I try to open it.

Does anyone have any advice on where I could go to try to get this resolved?

I have attached the vi in case someone wants to give it a whack.  Let me know if you can open it.  If you do open it, you won't have all of the necessary subs for it to run, but if you can at least get it open, that will help tremendously.

Thanks in advance.

Hi

It seems that your VI is corrupted. simlar problems have been faced by lot of other peoples in past. dont waste time in finding the way to recover your vi. just start with the latest working vi you have (If you havent taken any backup then take a lesson from this)

I had also faced a similar problem in past.

I was afraid of that. 

I was able to recover an older version of the VI from our automated network backup server.  The PC I was using hasn't been on the network for about a week, so I lost some recent updates, but twenty minutes in the block diagram got me back up and running.

Thanks for the warning, though.  So this is something that happens often?  Kinda scary.
