Hi Clyde,
You said you bought form B&H Photo so I guess you bought a boxed version.
In the boxed version you're supposed to have a plastic card where your serial and unlock code are printed on it. If there's nothing, please return your boxed version to your retailer to obtain a replacement.
If you bought a downloadable version, please contact B&H Photo right away if you didn't receive anything after your payment; we do not manage the license delivery of our retailers.
