I need help because my Minecraft launcher doesn't work...

It's been a long time I haven't played Minecraft and until now it worked nicely. But now that I want to play on it again and I run the launcher, this appears (click images to enlarge):

enter image description here

At the bottom left of the screen the profile names keep loading (normally my username appears in the box) and as you can see I am unable to click on the "Play" button.

I tried creating another profile but it doesn't work because soon after they ask to enter my Minecraft username and password. The password I entered disappears and it keeps loading (I've tried waiting like, 30 minutes and it still doesn't work) so this is definitely not normal.

So basically I can't play on Minecraft anymore (version 1.7.9)...

P.S. I use Windows 7.

Why is Minecraft installer not working?

Minecraft not working can be caused by outdated or corrupt device drivers, especially your graphics card driver. Graphics driver allows your computer to display the game correctly. However, it's not always only about the graphics driver, and the culprit may lie in the old sound card driver or network adapter driver.
