Unable to send or receive messages for the Hotmail account.

Server Error: 5102
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00002

I'm getting this message even after I deleted my account and added it back on.

There is no stuck message in my Outbox folder.

I can write/send messages even if the error message says otherwise but it won't sync/receive emails.

I don't know what to do.

Anyone with an idea??????
