"You are not logged into Windows Live Messenger"

After a user (a business representative user) installed the October Power Tools, they started getting a message saying "Team Foundation Error: You are not logged into Windows Live Messenger" when opening VS.NET 2008 Team Explorer.

I didn't look into it much (too many other things going on), but I guess these steps fixed it (or disabled whatever was causing the issue).

1. Open VS 2008 and wait until Team Members is not "working..."
2. Right-click on it and select Personal Settings
3. Under Collaboration, click Change
4. On the opened dialog select None and click OK
5. Click OK once again

I got them from this forum page.
