My windows live has suddenly stopped working and message comes up windows live searching for database, how do i get my live mail to open again?

yes the internet was down for while, thinking it was just me as sometimes may be an glitch in hydro i proceeded to reset everything etc.after short while internet came back on. When using google chrome there was no problems. Then i checked my email on windows live, a sign in box appeared so when i sign a message appeared live mail cannot be started,cannot be opened    searching for message database.( a scan automaticly comes on but shuts off)   possible problems they suggest is disk is full or memory problems.   OR i moved database.     Checked other things and found while off google chrome and on internet explorer the internet explorer was not there. not sure what happened so put on a restore and internet explorer is back but the windows live mail problems remain.  I HAVE WINDOWS LIVE MESSENGER is ok and hotmail is working ok    I PREFER THE WINDOWS LIVE but have the hotmail as backup and works ok, any suggestions as to fix this issue?
