Play test code invalid

I presume the code want originally invalid but I put my code in for my play test download. Then on the next screen clicked on "game base" and not "download" now it won't let me down load. 

First time tester I thought game base would give me some further information on the play test and maybe some things of concern to keep an eye out extra information and what have you.

Any help from an early official would be grand thanks. 👍🏻
