I just got a new MacBook Pro Retina Display 2.3GHz i7 8GB RAM 1GB Video Memory Friday evening. I got it just in time to download Scratch Live 2.4.4 and repurchase/install ME. I had about an hour to do all that after I setup the OS and some other stuff before I had to use it at work that night. That Friday night SL & ME worked fine and I liked the new look and features of ME. Today I downloaded/installed some ME transition plugins and figured out how to pin this version of ME so that it doesn't disappear when I change the window focus to SL. I didn't make any other changes to SL or my OS. I set up Sat night and when I started using SL & ME, no video would display using either deck, however the text I had typed in ME was scrolling across the bottom of the screen as it should have been. My volume faders were linked to ME and they were both fully up. Have I accidentally pressed the wrong button? Did one of the plugins corrupt ME? Something else? Please help!
