Hi, Since today I have a weird problem with a Logic Pro 8 project. When I want to play back the project in the main window, I have no sound, and the meters of all the tracks stay down and don't show any activity, although there are regions with sound, and no tracks are on "mute" or "solo" or whatever... the faders are up and all tracks are routed to "Out 1-2"... however, when I click on a region and open it, for example, in the Sample editor, I have sound again. Very weird. I didn't change anything anywhere, it just happened. It is also just this one project, all other projects still work. I have no clue what the problem is, since I REALLY didn't do anything... can you help me?
