This problem has been solved! Now Facebook Widget works fine
IF YOU HAVE THE MARKET VERSION OF LAUNCHERPRO INSTALLED:
-Backup current LauncherPro settings in Preferences (This will also backup your Registration number)
-Uninstall LauncherPro through Market or Settings->Applications
-Re-install the theme
IF LAUNCHERPRO KEEPS ASKING YOU TO ENTER YOUR UNLOCK CODE:
Use ADB or root explorer to delete /dbdata/databases/com.fede.launcher (Thanks to epicfailguy2)
Another problem is the following:
if you have installed Facebook app from the market, just uninstall it!
I hope it can help
