You need to be patient. some games take a long time to load, some others don't. I never had a problem while loading a game. You just need to be patient!
Also, you might not have the right Flash Player, but I believe that only would affect when you get to the game. You could just refresh, or wait it out.
Some games that have a lot of data with a com thats kinda slows, that happens. Just be patient and wait. This happens a lot with Sonny. So take yoga or something to make you more patient.
