Loading screen problem.

The first game I play during the day always gets stuck at 0% in the loading screen. I would have to control alt delete then come back in for it to start loading. Not a big deal which is why I didn't report this sooner. I'm reporting this now because today it got worse. I was stuck at 0% so I did everything I could think of including control alt delete. I was still stuck at 0% for a long time. After about 5 minutes, a box appears saying that I was disconnected. Please fix this riot.
