Ray:
After the shared-screen session we had on Thursday (Friday for me) I uninstalled CC 2015 entirely, including the preferences, and reinstalled it anew, but after installing the ServerBehaviorDatabase extension I still got the "Uncaught node.js Error".
After Googling that error a couple of times it turns out that it is giving a few other people a headache too. (Please check out the link below)

This is probably telling us that such error is not much related to problems installing CC 2015, no?
Meanwhile, I'm going back to using DW CS5 so that I can keep working on my projects.
Kindly let me know what's the next step to follow in solving the CC 2015 / Data Bridge problem.
