geez people, you all must be used to playing defense games like this because this is very hard for me. It took me a few hours just before i could beat easy , and i still havent beat medium! Great game though.
Here is a very helpful tip tat worked for me, and should work for you too.
When the game has a dowloading error or just a loading error, reset the computer (it stinks to have to do this, but it works!).
