Problem with MSN contacts in YM

Hello,

I am having the same problem as:

http://ccm.net/forum/affich 98597 i am using ym msn contact see me as offline

Some additonal information:

The MSN contact appears offline to me too. However, I can start an IM chat with them. They can see my posts but I cannot see theirs. I can see that they are actively using MSn because it says "<MSN user> is typing a message"
