I am using Windows 7 OS and Windows Live Mail v 2011

When I click the sign in button and get the pop up I enter my info and sign in but the top of the bar never actually signs me into my Windows Live Mail. I can click sign in over and over with no luck. I have uninstalled and reinstalled with no luck. I went to my daughter's house and downloaded it on her computer and signed in without any issue. Except my folders do not come up on her computer but all my contacts and mail come up perfectly fine. I would appreciate any help.
