In response to Rounik's question:
I created a new project on my new and current Mac. The old project was all recorded in Adobe Audition on an old mac, running windows through boot camp, I then purchased my new Mac Pro and transferred all the audio files to the new project and mac.
In response to Ski's question:
-I have 2 internal drives, one with all applications and everything on it and the other with all audio files on it. So all audio in projects is opened from there.
-I do have an external drive but it is pretty full and I use that as back up to what I have on the computer. I've always loaded music from the internal drives on my past computers and there's never been an issue. All the other computers I've ever had have been no where near as powerful as this one, memory, space etc...
-In regards to looping, I don't think I explained properly, I actually meant cycle mode, when you have the green cycle bar at the top on and the song just repeats over and over again. That is the main time is has this error.
-The 'more info' button leads to to a help section about the sudden motion sensor, which I followed their instructions and it still did nothing. Also, I thought that was only for Laptops that the sudden motion thing applied.
