Simulink Scope doesn't open at all

I'm new to MATLAB and I've been trying to simulate a simple RC circuit response over time with the scope on Simulink, but it refuses to open.

When I click on the scope (and I've tried the floating scope as well) the popup window appears in the task manager and in the opened apps list but when I click on it nothing happens. There was one time an error message showed up but just like the scope I couldn't even read it because it refused to open - at this occasion the main MATLAB page also died and just gave Windows error sounds when I clicked on it.

I am using a just installed R2015a MATLAB with a license provided by the university I study in, on a fresh installation of Windows 10. Maybe I forgot to add something on installation?

Edit 1: I found out that I can't open figures or plots either. I believe the problem is more widespread than I originally thought.

Edit 2: I gave up trying, had lunch and after about two hours I tried again. Lo and behold, it just worked!(?) Didn't change anything and it just poped back to life. Now I want to know why this happened...

Here is an image of the problem:

I found out what was going on. I imagine MATLAB was just opening the scope/images somewhere beyond the screen boundaries, because when I did right-click > minimize followed by right-click > maximize on the taskbar icon of the scope, it would readjust to the screen size and show the scope screen. That drove me crazy for a good amount of time, hope it'll help someone out.
