I am a student that uses limewire pro to transfer data around our class, without the hassle of converting it into a torrent, and giving people choices of when to download large files (e.g videos of molecular structure in chemistry). My music is legit, and I don't have any apps I would have to pay for. After experiencing random shutdowns on my macbook, I swapped the battery with my brother's and the problem continued. I then reinstalled OSX, just incase I had messed about with it and ruined something. I took it to my local genius bar, but as soon as the genius saw it he told me 'limewire is an unstable java program, it is causing the problems'. I considered uninstalling limewire, and seeing if the problems continued, but this would not help as the shutdowns can happen twice in a day, or once in two weeks, and I cannot go that long without it. Could there be any truth in this, or was he trying to persuade me to get rid of limewire as he thinks I am using it for illegal purposes. Any help would be kindly appreciated.
