Hey, hope someone can help me as my N900 was running great and now it isn't!

Since my phone updated itself yesterday (25\05), whenever I press on conversations, then press New IM, a box appears that says (No Contacts). It didn't used to do this, it used to display all my msn contacts that were on and offline.

I'm using the Pidgin Protocols Plugin for MSN, and always have. This is only something that happened since yesterday. MSN still works fine, I can talk to people and they can talk to me, its just a much more lengthy process to try and see who is and isn't online.

Why can't I see any contacts on the new IM list?? I hope someone can help, thanks guys
