I have the MAC version installed and everything was working great. Not sure if they are related but recently I took advantage of your Black Friday sales and added on a few packs. They seemed to all install but now when I open and want to start a new project, after a few minutes the screen freezes and then I try to shut down and everything goes grey but it will not close down. So the program just sits there and when I am ready to shut down for the night I have to go back and forth until MAC will finally let me close the program. I am not a computer wiz but I am trying to explain the problem as technically as I can LOL.. Please help!
