I had the same message however it did not occur involving plugins. What I did instead of wiping my computer, I updated Pro Tools and then checked the Pro Tools Aggregate I/O settings in the Audio/Midi Setup in the Mac OS. I didn't have it on the proper settings and so that's why it gave me that message. I switched to the proper settings. and Bingo, Pro Tools loaded properly.

Hope it Helps.
