Vista - windows live mail has changed

Hello All.
Can someone please advise me. I have windows live mail and last week for some unknown reason it has changed. I used to recieve my emails and they would be a mix of text and pictures, now they are all text with very annoying http links that you have to click on. this is driving me mad. and no matter how I try I cannot find how to change it back. I am not very computer savvy I'm afraid. but I find this windows live mail awful. I much prefered my old outlook express. even the button for searching for new emails is gone and I have to log in and out if I'm waiting for a new/confirmation email. thanks Tricia.
