Hi Danny,
Unfortunately I am unable to repeat the error with my fieldpoint here and your software. The only thing I can think of is to check all of the installed drivers and make sure they are up to date. Here is a article that points to the visa drivers not being updated as the cause of the error, but if you haven't recently installed new drivers on your deployment computer than I'm not sure why you would just randomly start getting error and why it wouldn't happen when the VI isn't in a project.
Let me know if that helps or changes any of your results and I'll keep trying to find a cause for the error.
If you change the IP setting back to the way they were, do you still receive the error?
