I had this same problem but only on select email messages received.  It won't open certain email messages but will open most of the total messages.  I went through the process you suggested and now my Windows Live Mail won't open because it says it is being used by another program.  I've tried to open it several times but keep getting this same message.  I restarted my computer after going through your suggested solution so I don't see how another program could be using my Windows Live Mail and won't let me open it.

Any suggestions?
