#10 App crashes when font not found

[Sam]

If the font file cannot be found, as defined currently in the application description xml, then the app will crash unexpectedly.
This may be due to some of the following reasons:
- Font file not defined correctly in the app description xml
- Font does not exist in the windows font folder
- Windows font folder is not in the expected spot
- Custom font file cannot be found

Exception handling will need to be added so that the application does not crash.
