I bought 2 licenses, but the second says it's invalid!

I have a key and for 2 computers. the second setup didn’t accept the key, it claims it’s invalid

Hi Erika, can you send me your licensing information to [email protected] with a reference link to this forum topic or a short description of the issue, I’ll check the license in our licensing system, and hopefully we can resolve it as soon as possible.

Thank you,
Paul
