On my mac I have been having trouble not being able to go on my premiere pro and it kept saying "not responding". So I emailed my teacher and he gave me anothr computer to do my projects. So I started it on the other one and now its also not letting me in. If I get lucky itll be there normally for 5 seconds then turn off and nothing pops up telling me something is worng. I have a pro book now. PLEASE HELP!!!!!
