Upon purchasing an email message is sent with your license key (request your key if didn't get). For all Professional features, you should get the software in your personal section. In other cases you may just enter your license key into the existing version.
If you buy DMDE Professional using credit/debit card there is an additional individual verification after payment to prevent fraud.
