After using MainStage for years without much issue at all, I installed the 3.2.3 update and suddenly I'm in ****. Previous concerts will not open without crashing MainStage. I also cannot use my Scarlett 6i6 without crashing the program. In short, it seems like anything I do that I would do normally on MainStage, I cannot do. This is a huge problem. We use MainStage for all our worship patches at the church and all my concerts for Easter aren't working. This is wasting my time and my volunteers.
