The requested package laravel/spark-aurelius could not be found in any version

Hello ! thanks in advance,

I buy one license, install spark installer, give github permissions and accept both invites... i do all right ( i think ).

when i use spark new project, i give this error :

Problem 1
    - The requested package laravel/spark-aurelius could not be found in any version, there may be a typo in the package name.

I don't know if i do something wrong... maybe some tips ?

Thanks !!!!!!
