Comm Errors with NI 3.1.1

[baybandit]

I have upgraded my software to NI V3.1.1 I  get the following errors with various SMAR devices using a Rockwell CN2FF linking device:

Read VFD List...Fail error- NIF_ERR_COMM_ERROR (Error Code=-11)

Open_VFD...Fail error- NIF_ERR_BAD_DEVICE bad device data (Error Code =-47)

I can go to the function block app, monitor mode, all data seems to be good.  The network is up and running fine. The devices that I receive the errors on change every time I log on (Via Laptop).  I have tested the network wiring and terminations , no problems were found.  What could be causing this?

I received the same errors using 2.3.6 before upgrading to 3.1.1

I've had issues with this in Version 3.2 of NI-FBUS Communications manager when I power cycled the devcie on the network many times.
NI would try to write new VCRs to communicate with the device but would write a bad VCR and then I would get those exact same errors.

The only way I could get that to work right was to write zeros to all the VCRs in the device and then delete it out of Configurator and let the device re-enumerate itself.
