VI does not open anymore

[vbs]

I have been working on a VI for a few Months not and it does not open anymore. The last change I did was on a Mixed signal graph

and now when I try to open the VI LabVIEW freezes at the welcome screen. Any ideas on how to recover this VI will save tons of work.

What message does it give you when you try to open it?

Do you get an error code or message?

Do you have a recent backup of that vi?

[vbs]

No error messages or Error codes. The welcome screen freezes and then I have to just kill labView from the windows task manager.

Unfortunately there were no recent back ups, The last back up was done in June. very frustrating.

If you don't have a back-up there is one possiblity...

My Documents\LabVIEW Data\LVAutoSave

may have something for you.

Otherwise....

The vi may be in run-on-open mode.  You might try creating a new blank vi and adding the vi to the block diagram and try opening it up from there.

Good Luck.

BEFORE using the one Ben suggested, make an extra copy... just in case.

Always backup your code.  On a daily basis if possible.  Look at using a Source Control application.  For single users, there are some 'free' versions that you can download.

Why would that freeze LabVIEW when being opened?

[vbs]

Nothing in the AutoSave folder!!.. What a bad day.. I have been reset by 2 months. No error messages, No ways to recover, Labview just freezes when opening this file, I tried to place it in a blank VI that does not help either.

As a shot in the dark...

try opening the VI in a text editor like Notepad to see if a data file got saved over teh VI.

I could not make out if there was a data file overwrite by looking at it in notepad. Would you like to help I have attached the file.

This VI referes many sub VIs so you might not be able to open it in LabVIEW.
