I'm having this same problem for the last two days. It started with the error :"Failed to connect to DSP engine (Device has not been initialized properly [code -8201]". I manually tried to sign in and now it tells me my trial has expired, when in fact I registered through a license and have been using it for months... This likely happened after updating my PC BIOS recently...
I am running Protools as my DAW. This is paralyzing work that I was doing- completely unacceptable!
Please help-
