I'm stuck in loading screen for 20 mins

It's been a few days now that I'm stuck in a loading screen for more than 20 mins. I tried reloading, uninstall and reinstalling Minecraft with Cd. I tried putting my WiFi off and back o  and still we can't access Minecraft...

 

I'm not sure why this is happening. My son is making me loose my mind because I can't fix it. Please help us.
