Everything was fine until Feb 15.  I use Windows 7, Windows Live Mail 2012.  I can receive emails but cannot send/reply.  When I try to send I get the message " a problem occurred while trying to open this message".  I had my internet provider tech help me research the WLM log and he discovered the following error  ID - 0x80070005 - I am extremely dependent on using email for my business, so please help quickly !
