vi not opening

[Cadbury]

Hi

I cant open a vi which was developed in 2009.I was very well using it. Suddenly from one time on wards When i try to open ...it tries to open , suddenly entire labview gets closed.

My VI can't be opened any more. But the same vi in the other systems it is working fine. I converted it to 8.6 and tried opening it in my system it is opening and working fine. What  problem might have occoured. Mean while i didnt install any software like that  in my system. Other software vi' s in 2009 is working in the same system . Any way to recover my VI for 2009 ? Please help.

So if you opened it okay on another PC and was able to save it back to 8.6, and are now able to open it on your PC, are you opening it in LV 8.6 or LV2009 on your PC?  You say it is working fine now.  If you can open the 8.6 VI on your PC, allow it to convert itself up to 2009 and save it.

If the VI still causes LV to crash, are you getting any error messages?  Any messages on restarting LV2009?  Perhaps a crash log you can post so someone from NI can interpret it?

Thanks for you reply.

Actually i'm not getting any error messages.It closes te entire Labview. thats it.

The vi is working in 8.6 currently in my system.

When i open it in 2009 the same problem occurs !

Why don't you post your LV 2009 VI that is crashing here so we can see if we can open it?

Pls find the attached vi

It opened up fine on my PC (LV2009SP1).

The only things I noticed were

Everything inside was disabled (broken up between two diagram disable structures.) 

There were a lot of Call Library Function nodes.  (Issue with .dll?)

A ridiculous number of stacked sequence structures including one that has 25 frames.  (This shouldn't cause a problem with LV crashing, but it is bad programming practice.)

I would recommend trying a divide and conquer approach. Perhaps it is just one item in there causing a problem.  Open your VI in LV 8.6 and delete half the code, save, then open in LV2009.  Try the other half.  Keep trying to save your VI with different portions deleted to see if you can either get it to load or crash.  Perhaps delete all CLFN's and try to load.  If you can narrow down if one or more pieces of code are causing the problem, then maybe you can not save those and readd them later, or work around them in some other way.
