I just bought MATLAB 2010 Student Version and installed it on my Mac but it doesn't start, it just bounces in the dock and crashes. I've googled it, but still looking for a solution.

I noticed I don't have X11 in my utilities folder so I went to X112.6.0 and got XQuartz. I'm relatively new to Mac and was wondering if it was the same as X11? I would of just gotten X11 off the Mac OSX disc, but I have the Macbook Air and don't have access to a CD drive right now.
