Windows 7: Msn hotmail

Hi all need to ask .I me and my son did a repair install of windows 7 on his computer( should of done a clean instal like i did on mine) but he did not want to lose all of his stuff ,he almost has a 1tb hdd falf full. So we did it and it works fine, all but the email he can sign in to the mail account but the page look out of wack ,it just loads for ever and you cant click on anything,, I did all the things in the repair install where it says you may not be able to sine into WLM even the comand promt thing any idea's what i can do to get his mail working agen?

how about installing Windows live Essentials 2012, it will come to a screen and you can pick Windows Live Mail only, once it installed you can set up your msn account or wlm account in the account settings.
All his emails will come in when you login and so will all his contacts

I did instal WLM 2012 and it still did not work, but i did get it working the next day , i got my laptop to read my emails to see if i got any replys here .my sons email was set to hot mail so just for kicks I chaned hes email to outlook just to see what that would do, I got on his computer and looked at his email and thire it was it was set to outlook and all is fine now, on his computer I could not chang any thing ,I dont know how but going to a other computer and changing it worked.
