Because it would open InDesign CC instead of CS5.5. I'm temporarily using another person's account to use CC so I can open up some work files that were assigned to me. Said file, was made in CC, meaning I couldn't open it using CS5.5. Problem here is, it changed the default program for opening INDD/IDML, so on and so forth to use Adobe CC, and I want to change it back to CS5.5.
Also, I hit "pick as a solution" by mistake. Can that be undone?
