The error tells you everything we can, you have a disallowed program or driver, Have you updated your drivers lately? or used beta drivers? or you could have a disallowed program running in the background so close anything besides PR and see if that fixes it.
I just got the same error message last night. I believe its a conflict with mumbles overlay and the new pb update that was just handed out. If you have mumble overlay on, disable it.
If you don't have mumble overlay on, then start with the basics. Get rid of every process not needed, every plugged in device, again not needed. If it then works, start plugging things back in one at a time. Also with the processes.
