Hi bbwpdad,
Did make sure to create your obj or source file for External Compiler Support with the latest version of your UIR file? I think the first thing I would try is to rebuild that by going to Build>>External Compiler Support and click create, then replace that with the one in your project.
I tried this out using CVI 8.5 and had no problems. If you are still having problems tomorrow I can try it in CVI 6 to see if there are any differences, but I think it should be about the same.
