Now instead of doing all of the steps you could just enter the numbers above I just wanted you to know where I was coming from.
And to tell you how to get on command prompt at school ;)
If anyone can find a better method please post it and put a link in the comments I will be interested to know

To get games to work...
Ping Files.sharenator.com ← Ip 220.127.116.11
On the browser with the game you want up open the page source.
On Firefox its View → Source. Hit CTRL + F (find) and type .swf
Copy the whole link and paste it up in the search bar. Then replace the Http:\files.sharenator.com with 18.104.22.168 and hit enter.
