Dudes, you paid $10 (or in the cases of the people who went to bars nothing). What did you expect for $10 a hand job from your computer with your flawless streaming HD on your 1995 laptops? C'mon people everyone knows that these streaming services to thousands of people at once are incredibly difficult to pull off. It's the same reason your cellphones usually don't work inside stadiums.
If you haven't figured it out by now, until the technology is perfected, you have to login early to these things to avoid the rush of people near kickoff time and if you don't have a newer, more expensive computer with good processing speeds and a faster connection through your isp, then you are screwed.
