Without beeing unpolite; isn't it better when you try to catch file opening problems instead of letting your script die...
I could imagine your daughter isn't able to restart the application her-self ... Generating an error message and letting the application return to the screen it came from seems a more humane variety then die (not only for the disabled...)
I've tried to run it, but after five minutes of trying I gave up. I'll try again tonight ;-)
Anyway... Keep up the good work!
