I just posted this in another thread...
This is a web based game, so we play the game our computer lets us
play. I had loading problems as well when I joined this site. The
fix, for me, was when I changed browsers. Also, try turning off
anything you don't need in the game Options, and lower the flash
setting.
If you haven't done it yet, check out the System Requirements in the Getting Started section over there-->
