my pro tools stopped working all of the sudden when it is booting up it dose not recognise any video hardware connection and it says video engine failed to initialize and this is the error message that it gives me after;
could not creat a new document because Assertion in "/Volumes/Development/ws.ProTools_10.3.6/AltraPorts/DFW/MacBuild/../Views/UMenu.MacOS.mm", line 1351
Please could someone tell me what needs to be done?
