Windows Live Email 2011 in Win 7 stops responding and crashes on loading

Windows Live 2011 email fails  to load and says it has stopped responding but does not provide any information as to why. It  then closes down without opening. Have tried repair in Uninstall programmes and gone through the knowledge base and tried Microsoft Fix It tool without success. Would it help to download Essentails 2012 and reinstall, and/or do a cmd clean install ? Is the issue too many historic emails ?  if so can these be managed outside of the programme which is currently crashing ?
