How do I fix a vi with a Fatal Internal Error, "graphobjs.cpp, line 56"?

All of a sudden the vi won't open (on my computer or on another in our lab).  it appears to make an attempt, but before it opens the error message box comes up.  Don't know why the vi have become corrupted or what to do to be able access it again.

Which version of LabVIEW is this?

If the dead VI calls sub-vis it sometimes works if you open all the sub-vis first and then the dead vi, i.e open it from the inside out.

I'm running 7.1.  The labview engineers opened it up with the latest version and back-saved it to 7.1 and sent it back to me.  It works now.  Now i'll see if i can find the prolblemic vi.

Thanks very much.
