LabView starts ok but crashes when try to open "block view"

[Irene L]

I'm running LabView 7.1.  It has been operating fine.  But all of a sudden it starts crashing.  I can start LabView.  But as soon as I have opened a module and try to run it, it crashes.  Sometimes it also crashes when i try to open the "block view", and sometimes it is not even able to complete loading certain module.  Is it a computer memory/resource problem?  But I checked task manager and there is nothing running on the computer other than labview.

Hi,

Is it certain VIs or all VIs. If its all VIs then you might try doing a repair / re-install your labview.

If its certain VIs, its possible they have been corrupted. If this is the case, you will have to regenerate them.
