I'm guessing I've got an older version of Flash player or something, but it shows up in the top left corner of a blank game window. Other than that, I have no idea what's up with this.
It would be best to upgrade to flash version 9. Other than that, I'm not sure what would be the problem. I would suggest upgrading though, that might be the problem.
Certain games I have tried to play just stop after the Armor Splash and their own personal splash and have "Debug:" appears in the upper lefthand corner of the game window. Happened twice today. Towering Forever, and Hunting something or other.
