I can send messages on Windows Live Mail, I cannot Receive Them

My Windows Live Mail has suddenly stopped receiving messages.  I looked up a thread on the subject and went through the Windows Live Mail Essentials repair procedure, still cannot receive messages.  I'm guessing I might have to uninstall and re-install, but afraid if that happens I won't be able to get the password right, at this point the password is automatically remembered.  Any help would be appreciated, this is my only email account since I had trouble earlier with a second Live Mail address.
