MATLAB 2015a doesn't load

I've installed matlab 2015a on my new win 7 x64 system. When I launch it it gets stuck on the MATLAB startup screen. Iv'e tried to follow the next article, with no success: http://www.mathworks.com/matlabcentral/answers/37772-matlab-gets-stuck-in-the-initializing-state-during-startup-from-bat-file I left it loading for about 30 min, but it never opens. Any ideas?

Hello, I have the same problem on 2015b on my linux machine, too. MATLAB just sits there in its splash screen. Why is this happening? What is the solution? I paid for matlab and I cannot use it; really sucks. [edit: solved my issue. Read my solution down on the comments]

Erenca, contact Mathworks for free installation support.

Hey, I did contacted the support. And with the help, I could solve my issue. It turned out that I had not had the permissions to read and write on the folder /home/mycomputer/.matlab, on my Ubuntu 14.04. So using >> sudo chmod ugo+rwx .matlab to the folder and all the subfolders and files, I gave myself the permission to read, write and execute. After this, my problem was no more.
