Emails appear to download but inbox empty

Please can anyone help with this Windows Live Mail problem?
Suddenly my incoming emails have stopped appearing.
When I click send and receive they appear to be coming in but nothing is in the inbox.
I have checked into spam and other folders and they are not there.
I know I am getting emails because they are coming in on another computer.
It appears I can send because a sent message does come in on the other computer.
Thanks in anticipation.

PROBLEM SOLVED!
Silly me - had the incoming dates button wrongly adjusted and wasn't seeing the new emails coming in.
Sorry.
