MSNP15 broken?
This morning I tried to connect to MSN with my preferred client pidgin, which uses the newest MSN protocol version 15. But it seems that Microsoft changed something, that does not allow clients using this version of the protocol to download the Address Book. Very clever move. That includes Microsoft’s own versions of Live messenger.
To ommit this you have to use a client with an older version of the MSNP.
Pidgin users can use msn-pecan atm. Get it at http://code.google.com/p/msn-pecan/
