I ordered a 4 camera license, received a code almost immediately, that is an invalid code. I've apparently been ripped off and need to dispute the charge with my credit card company. Buyer beware!

None - they took my money and sold me an invalid license

Because you used theDSM beta version 7.1 the license key cannot be checked. If you downgrade to 7 the license key will accept and you can upgrade again to the beta version.
