First of all , sorry for my English.
I am using the Materialize framework in Meteor and I am with the following problems:

1 - Error trying to do the " deploy " .

C:\Users\Thiago Saad\Desktop\project\pkleague\pokemonleague>meteor deploy
Talking to Galaxy servers at
Error deploying application: Your account is not authorized to deploy to Galaxy.

2- Falling server with the following error :

Type Control-C twice to stop.

=> Client modified – refreshingbuffer.js:25
