inDesign AND Acrobat DC will not open! They were both working with no issues until 11:00 last night. Today, I just get the 'wheel of death'. Acrobat opens and then says "not responding" so I have to force quit. InDesign looks like it's opening - the dock icon starts bouncing like it always does, then nothing. Also the "not responding" message.
I have no clue why they both suddenly won't open, but I can't be without them and need to figure it out! As suggested in an Adobe Community post by Srishti Bali, I went back to inDesign 15.0.1 and did a restart, but had the same result.
