How to get a license for litchi pilot beat

I am a fresh man to use litchi. I have downded the New Litchi Pilot BETA app. But where can i got the license to use this app. thank u very much for replying this

I think they have reached the limit of Beta testers.

yeah, when i use another mail address to apply for beta test. It showed me that hava reached limited tester number. But i have downded the beat application. More details: the email address that have received the beat application download link is different with the account that i login into litchi pilot.
