Carriers Not Working

[smsjaipur]

Hello Everyone,
Recently I have installed presta shop script for my web hosting website.
I have added a single product to test this.

But there are some problem in checkout, it is showing an error always-

"There are no carriers available that will deliver to this address!"

My products are digital and downloadable. Hence I don't need any carrier.
But still I have configured 3 carriers, but no one is working.

Please suggest some solution. I have read a topic about same problem, but it was in different language and I am not understanding.
Please suggest.

Thanks
