Hi Pete,
I'm assuming you are using LabVIEW RT 7.1, since that is a requirement for using DAQmx. Here are my responses for your three issues:
1) You are correct in assuming you can upgrade the DAQ drivers in the manner you outlined, normally that works fine. However, as the following KnowledgeBase points out, the list of dependencies vary for different installs.

Do you have LabVIEW RT 7.1.1 installed, which appears to be the required dependency? If not, you may download this from ni.com>>Drivers and Updates

If so, but the problem persists, please post all versions of your software so I can determine where the incompatibility lies.
2) After we take care of upgrading the DAQ drivers, let's see if the 88705 error goes away, it might take care of it.
3) Again, all the steps you described are correct. It might be that all these problems are related and due to a bad install of NI-DAQ.
When a number of software issues like this arise all at once, it might be best to just re-format the controller and perform a fresh install of everything. Often times that will correct the erroneous behavior.
