WIndows live mail opens normally and receives mail from my BT mail server but I cannot open the e-mails. When I try to open a message a box appears saying 'a problem has occured while trying to open this message - a problem has occurred please try again'.    Happens with all messages.

Never had this before windows 10 but that might be a coincidence.  Tried repairing all windows essential programs  says successfully repaired) but still problem persists. Tried uninstalling and re-installing WIndows Essentials but problem still persists. Also contact list is blank (there were over 100 contacts on it but they have gone).  Any ideas anyone?
