If your program crashes, you can try the following steps:

Make sure wireless is turned on and you actually see the wireless icon before starting the program, this may mean that you have to wait a bit before starting the program after starting your Zune, be patient, it should only be a few seconds.

Try plugging it in and running the program in debugging mode in Visual Studio and reporting the Exception it throws.

If you get errors with the fonts:

Make sure they are correctly installed, see the home page for instructions.  You can verify they are installed by opening up any office program or something similar and making sure you can use the fonts there.

If nothing else works, you can always just edit the spritefont files to say any font you know you have installed such as arial.

If you have any other problems, you can post in the forum and someone can help you or you can contact me.
