I haven't been able to send/receive email on my msn.com account since yesterday, 5.12.14.  This is the message I'm getting:

Unable to send or receive messages for the Msn  account.

Server Error: 0x800488EB
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x800488EB

I have read through the discussion threads for similar error message but it is sort of all beyond my expertise.  I'm tech-challenged so really need someone to take me through step by step to resolve this issue.
