test.ly doesn't work

[Kevin]

Hello,
Thank you very much for this program. My daughter can't wait to get her
hands on it. Unfortunately I'm not having any luck with it.
I have windows XP Pro
I downloaded the file and test.ly - it appears in the web page and I have
saved it as test.ly

When I run it XP asks what program, I chose Acrobat as this is the only pdf
viewer I know. It then says it is an unsupported file format.

Is there any thing else I can do?

Thanks for your time

Regards
Kevin
