This occurred to me too. Somehow when you click VM Pro 16.1 upgrade within application it directs to an international website. It looks like VMware USA, but is not. The license provided at checkout will not be registered at Digital River. Digital River will have no transaction. The licensing to USA oppose other countries is messed up.
