Hiya
Are you by chance on v.0.8.1.1 ?
If you are you need to re-authenticate the FB widget. Here is a snip from Fede's log @
http://www.launcherpro.com/

I just made a very, very stupid mistake. When I was trying to register Launcher Pro as an app on Facebook, I kept getting an error that the app couldn’t be registered. After about 10 tries, I managed to successfully register it.
Today I went to edit the settings so that the posts would include “via LauncherPro for Android” instead of “via Launcher Pro” and noticed that all those failed registrations actually went through. So I started deleting them, only to accidentally delete the one that LauncherPro is actually using.
That means that the key that LauncherPro uses to access the Facebook API is no longer valid, so your Facebook/Friends widget will stop updating form Facebook.
I’ll be uploading a quick fix update in a few minutes, but it does mean you’ll have to re-authenticate your Facebook credentials by pressing Menu > Preferences > LauncherPro Widgets > Facebook Widget > Facebook Login .
Edit: The update is now in the Android Market. Please update to version 0.8.1.1 and re-authenticate as stated above to keep your widgets updating normally. You can also download the
APK file here.
I’m terribly sorry for the inconvenience and hope you can understand.
Fede
