Hello,
I think you posted your question in the wrong forum...this forum is for questions pertaining to the National Instruments product "Measure for Windows". In order to get the maximum exposure to an appropriate audience for your question, I recommend you post in the Measurement Hardware >> Multifunction I/O category.
Nevertheless, I will venture a guess as to why you are seeing this problem. If you brought your VIs over to LabVIEW 6i in an LLB, then you may have saved all the DAQ VIs (AI Config, AI Start, etc.) into that LLB. You should not have done that. LabVIEW needs to use its own copies of the DAQ VIs (in the vi.lib folder), not the ones in your LLB. There is a utility on the NI website that will go through an LLB and remove any vi.lib VIs from
that LLB...you should use this tool on your LLB, then re-load your VIs. I searched ni.com for "removing vi.lib" (without the quotes) and it was the first link that came up in the search results. After using this tool, your VI will then link to the DAQ subVIs in vi.lib and I imagine it will run without errors at that point.
If this suggestion does not help, you will probably get the best suggestions from the aforementioned Multifunction I/O forum.
Good luck, and have a nice day.
Darren
