Rids,

It sounds like the demo mode is timing out on you. It counts the number of shader evaluations and on that sample file it will run out real fast, since there are quite a few Surf and Beach shaders being used. Try playing with a single Surf or Intersect in the color channel.

I would like to add Paypal to the payment options, but last time I checked, they don't support a business model where they collect and remit the appropriate local taxes. I'm not set up to collect the sales tax (except in Pennsylvania, USA, and even there it's a pain), VAT, etc. and don't want to add that overhead.
