hello there to yahoo.. hope all is great

I have the following problem, when I sent a Yahoo E card and closed it as always by clicking done, It returned me to the "compose a message" page and has been stuck there for the last 5 days now. I am unable to do anything with my account besides write emails..I cannot read new mails or nothing.
I really hope somehow something can be done because i really need my email to be active, otherwise i will have to cancel my yahoo and get another account with someone.. please help me..thanks in advance
