Patrick,
What happens when you run the configure script (proe2pv_config.exe) and hit the test button? Does that connect? The other thing you might do is run through the CAD Worker side commands by hand - there is a decent explanation on how to do that in the
ProductView® Adapters Installation and Configuration Guide
But I am not sure you are even to that point yet, but I think it is what I would do to try and gather some more data.
