My former hotmail a/c which microsoft changed months ago to outlook has not worked since Jan. 19.

My hotmail a/c which months ago Microsoft changed to outlook has not worked since Jan. 19.  When I open it I see my folders but cannot open them nor any emails which I am now getting on a different a/c but I want my folders.  I have Windows Office 2007 and XP which only allows me to have internet explorer 8.  I've written every day to Microsoft and they acknowledge receipt but the problem persists.
