This is why you have had the time-out.
Facebook application is implemented in an old-fashioned way it does not load UI as an external SWF.
The fact that it displays the time-bar does not give any usefult information regarding the problem, unfortunately.
The same with mini-view of the widget - it displays User Interface in another way.
Can you open this SWF in browser? This is the User Interface that is not displayed on the widget.

Note that when this SWF is opened correctly you should not seen anything

Does the browser give you an error?
