Why doesn't my YAHOO work anymore?

It takes minutes to get my emails loaded. When i try to play cards a java error keeps coming up. I just downloaded latest java. It doesn't make any difference. I get into a card room and nothing clicks off. It's not my mouse. I can't stand it. I've been on yahoo for years with NO problems. Now im sick of it. I just keep clicking away and nothing happens. Please somebody help me.
