I recently reinstalled windows xp now some apps won't load

I recently reinstalled windows xp on my computer. Everything is working well except some of my apps(games) that I play online won't open. I read dr.infernos pages about newcomers to GeekPolice and did everything it said about java and the rest. These games are through playdom. I'm thinking that maybe there is something i need to download to get these to work properly. I'm using Google Chrome. I have tried to contact playdom but they don't seem to want to respond. I have no clue what would cause this or what to do. Can anyone help me?

have you installed net.framework and so?

I don't know what that is. I know I downloaded my network drivers. Is this the same thing??

I googled net.framework and came up with a 4.0 package. It gave me the option the repair or uninstall so I repaired it. but it didn't do anything different. Is there anything else I can do or is the problem with the site? I appreciate your assisstance and any in the future.

have you tried playing it in firefox?

No i don't have firefox but i will try it. I really appreciate the help. I drive trucks for a living so I realize I am not on all the time. and also appreciate the patience in between replies.

try playing it in firefox and tell me what happens...

Firefox will not even load it at all. Niether will internet explorer. I'm starting to think that maybe it's the site but i know other people that can access it. I just can't help but to think it's something i did not reinstall.
