Element is already the child of another element Error Again on PivotJitServer

If you get into this error on PivotJitServer don't panic.
Just open the MainPage.xaml and perform Format Document and Clean Solution.
After you Build the solution everything should be ok.
Strange error this one :) 

Element is already the child of another element Error on PivotViewerSample

I started to play a little with Pivot Viewer, but unfortunately from the first sample that you can download from http://www.silverlight.net/learn/pivotviewer/  I had an error
"Element is already the child of another element"
After searching the net a little and with no easy solution adder than get the latest version of Silverlight 4 toolkit that unfortunately didn't help , I've started to remove elements from .xaml and .cs
After removing all comments and formatting the Style.xaml I was surprised to observe that everything was working.
So I recommend you to do the same , I don't know what the proablem was but now is working just fine.

Just in case here is another archive with my working example:
