Hang during VI loading - possible version issue

Question

I've got a VI with many sub-VIs that when I try to open it the Loading dialog box eventually gets stuck in a loop where it goes back and forth between loading 2 different VI's.
This VI was written in an older version of LabVIEW, I think 7.1.  I'm trying to open it in 8.5.  I don't have the 7.1 disks anymore.
When I try to open the VI, the dialog box pops up that says: "Loading: <filename>.vi" and it goes through several files before getting stuck as described above.  It'll hang forever so I never get any error message.  I tried mass compiling but that eventually hangs as well.  I attached the log from the mass compile.  It doesn't always get stuck on the same VI so I haven't been able to narrow it down to a particular file or files.  
I copied and pasted all the files from a different computer and the same VI works on there (with Labview 7.1).  Any suggestions about how I could fix the problem would be helpful.

Hi Scott,
Can you perhaps provide some screenshots of what you see when trying to load that VI? 
Also, are you able to load a single VI instead of your application?  That would be a good way to conclude that the problem exists within your application.  Perhaps you can create a very simple VI in 7.1 and try loading it 8.5 and see if you experience the same thing.  You can also try loading some of your SubVI's separately and see if some of them can load but others cannot. 
Did you change the location of some of these VIs?
