"Error code 15: Could not load default data" opening vi

[zpm]

Hello, hoping someone has run into this before:

I've been getting an error when trying to open a few VIs from a larger project, the rest seem to open just fine.

"LabVIEW load error code 15: Could not load default data"

The files were created on an earlier version of labVIEW (7.1 -> 8.0) on the same OS and open just fine in 7.1 on the same machine.

This one is a small program that is definately a kludge, I've included it below. Not sure if the others are similar.

Thanks for any advice you might have to offer.

Clarification: This seems to be the only one that is causing problems.

Voila!

I had the same problem you were having trying to open the VI in LabVIEW 8. So I opened it in LabVIEW 7.1 looking for suspicious controls. Everything looked normal, except that one of your ring controls, the Class ID control, had a large number of items. (It honestly isn't that many, but it stood out as a possible source of the problem.) I converted the ring control to a temporary custom control and deleted it from your 7.1 VI. I then successfully opened the VI in 8.0 and added the custom control back to the front panel. So the copy below is saved in 8.0 and should work fine for you!

I'll try to do some more investigating about what exactly failed in the upgrade process.
