This is the first time I've posted on here and I just got my first iMac a couple weeks ago. So I'm very new to the whole system. For the most part I feel like I figured everything out, until this issue. Somehow I must have changed some settings in iVI and now whenever I try to open the app it moves all videos to the program and it just locks up with the rainbow wheel spinning. I've let it spin forever (days)with no luck. I've tried to open the program holding shift and then it just won't open at all. I've deleted the program and reinstalled it and it does the same thing. Please give me some ideas on how to fix this!
