Changing to improve, but making it a problem for little old me!

I received numerous messages that since you were updating I should use my outlook or outlook express to send and receive my mail. You wanted me to update my SSL. But I have a very old, slow computer and am not sure how to do this even with your help site. Now it seems that I am not sending or receiving my mail properly as you stated would happen. But I do not know how to correct the problem, and I never use my Outlook program and all my contacts are in yahoo on line and do not seem to be in outlook. You have really made it quite difficult for me now, what do I do? Joi
