I was a little confused by this as well because the package was updated to a new version then a few hours later unable download - so im guessing everyone who ever has usps has to email him for the upgrade ??
The developer has notified that he is unable to continue developing and supporting this for new users and new versions of concrete5. It is effectively withdrawn from the marketplace and no longer available for download. The developer will provide base support for existing users, but does not want new users, even unsupported.
How do I contact the developer to request support? Should I expect an upgrade or update that will allow my customers to have a choice of shipping options other than USPS Express. Otherwise this product is no longer useful to me. Would C5 offer a refund if the product is no longer supported or relevant?
