@ Twlighting and adover211, my apologies for the delayed response! Things have been hectic, just finished moving, unpacking, wife had a baby, etc.
I put this project on the back burner as I became preoccupied with the above, but I tried this morning and it was a success! I had tried this exact procedure back in August, logging in to the MSI "Authentication Server" and then trying to activate the EID, but it wasn't working then. My guess is they were in the process of implementing this routine when I previously attempted.
I was able to utilize my single issued wideband EID to unlock both CPS16 and 2.0 on the same computer. Looks like as long as the MAC address is the same, you can unlock both versions with the same key.
Thanks for the follow-up, hope everyone is having a great week.
