The module makes some calls by curl to validate the license.
It seems like like the license number is restricted to a domain name. So if
@d-shilko have a license number, it wouldn't be valid for your url.
However, it shouldn't be that difficult to null this module.
I could upload a version that probably work without a valid license. But I'll wait for
@d-shilko's response. I know he also can null this module, so I don't want to "steal" the credit.
@d-shilko Do you have any knowledge about the file .info, that's located in the root of the zip?
