The message suggest to re-install Matlab. So do this: install it over the existing version.

@Tisha Sikder: No, you do not need to uninstall. I mean "re-install": Install Matlab again.

Call them on the phone (before the weekend!). Tech support is free for installation for everyone, even students. Yes, talk to a real live, friendly person who will talk you through the entire process.
