Invalid XAML suddenly in DataTemplate for longlistselector items (WP8) - xaml

Question

Had this error a few days ago and it seemed to go away. Now it wont go away. I am also getting an Adcontrol error: ApplicationId and AdUnitId need to be set before using this control Adcontrol is set up the exact same way in another app so I don't see what the issue is and cant find any information on it.
EDIT:
If I remove the portion of the code with double brackets }}, the Invalid Error goes away. I removed the Adcontrol all together to isolate the error as well. However, when I run the app, I still get this:
**A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.ni.dll
Additional information: Could not load file or assembly 'Microsoft.Phone.Controls.Toolkit.resources, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.**
I have uninstalled and reinstalled WPToolkit. Im using similar code and WPToolkit in another app and it does not give me this error. What else can I do?

When I run the project I get the following. I continue after each one, and the app runs, but the Pivot Headers are all screwed up but app seems functional.

Additional information: You can not use PubCenter IDs for testing in the emulator. If you want to test with these IDs, please deploy your application to a device. Otherwise please change your ApplicationId to "test_client" and AdUnitId to one of the supported ad types as outlined in the documentation.

if you are using windows phone toolkit then
you have to include
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
xmlns:cc="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
in your *.xaml page
