If the game wont load, try to shut down everything else, upgrade to the latest flash, and/or trying a different computer/game.
If you have completed the challenge but the points/badge doesnt come, WAIT. READ the directions carefully. Sometimes you have to hit SUBMIT SCORE.
If Chat wont load, relax, try a different one, or just wait. Kongregate isn’t perfect (yet).
If you cant find a particular challenge, even after you’ve gotten the check, see if it has more then one game (specifically for the double card challenge, Castle Crashers and Doeo).
If it still doesnt work, yell at Greg….
