Cannot read any message in my Hotmail Account

Hello,

For the last two or three weeks I have not been able to check and read any e-mails in my Hotmail and Yahoo account.. I can see that there are new e-mails in my Inbox but I can not read them, open them, delete them..
whenever I am trying to do something in Hotmail Inbox it seems it just downloads something which will never end.. For your information.. I can see all those item located on the bars like ( home, profile, people ) are displayed on the left side of my screen..

I am fed up with this problem.. help me..

best wish
