Why wont yahoo beta mail let me in despite my downloading the Windows XP Explorer 7 update as directed? -

I have used Yahoo Beta mail for some time (it really is better!) but today it would not let me in, saying the browser was incompatible and referring me to free downloads. I spent ages downloading Windows XP update 7 Explorer but I still can t get into Yahoo Beta Mail. Can anyone help? Also it is frustrating that Yahoo do not appear to have a help phoneline in UK. Does anyone have it?

I sure do have the number! 0207 1311000 To get a Customer Services operator, say your phone doesn t allow calls to 084, 087 or 09 numbers. They should be able to help you over the phone. Good luck .
