Download Previous Version of Matlab

Hey!

I've just purchased the latest Matlab available, 2014a. Because of display problems on Mac Book with retina display, I would like to download the 2013a instead which uses the Apple Java.

It's impossible to work with the latest version as all is blurry on screen and for a guy with glasses it gives a massive headache and puke sensation.

I might add that because I am a student, I purchased the student version. On the "My Account" page I don't see any option that would let me fulfil my wish.
