Yahoo games, chats, and plug-ins aren't working?

[Brittney]

Before the other day, I had always used Yahoo version 8.1. But I decided to try out version 10 to see if it was any good. Well, like I had thought, it wasn't. But before I had gotten rid of it, I ran Y!AddsBlocker - http://www.technixupdate.com/get-rid-of-ads-in-yahoo-messenger-10-with-yaddsblocker/ - which is supposed to remove the ads of Yahoo with version 10. It removed them, but I noticed the chats and etc were not working. Because of that, and the lack of appeal I had for the new Yahoo, I went ahead and uninstalled it and re-installed Yahoo 8.1. When I did that, I noticed the chats and games and plug-ins STILL weren't working. After numerous attempts of uninstalling Yahoo, and even deleting the registry strings, I cannot get the chats or games or plug-ins to load. I'm not sure if what I installed with the ad remover was a virus, or what. I even tried re-installing Java because I thought it might have something to do with that. So, can anyone help me out here? Thanks.
