damn....when i want to share a file (like, a 5 MB song), it goes veeeeeeeery slow, and when it goes to the half, id stops sending an d a message apear "error sendidng message to bla bla....."

what can i do?????????

That is not a bug.
That could* be because of your connection, or your friends..
Have you tried with other contacts?
Or, the server is having problems..

what does the server has to do with this? doesnt msn only send though server when a direct connection can't be established?

is only the specific file or all?

If either or both of you have a router you want to make sure you have UPnP enabled to help speed up the transfer.

I think wlm's transmitt speed is a little slow than msn 7.5
