I have about 5 email addresses that I use this program for, all of them either hotmail or live addresses, and just one of them is having issues. Every time I open WLM, all of them download their new emails just fine except this one. It fails, every single time now for more than a week, with the following error message:

Unable to send or receive messages for the (editedout) account.
Server Error: 0x80072EF3
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80072EF3

What gives? Why is it just this ONE email address that is giving WLM fits, and how in God's name do I fix it? I have searched everywhere I can think of on 3 different search engines and nothing - NOTHING - is giving me any help at all. This is my last hope. Please, help me fix this. This is my main email address we are talking about here, and if WLM can't retrieve messages for it then the program and is worse than useless to me. Thanks in advance.
