@Francis Apel not sure if it applies but I originally had trouble copying and pasting my Twitter api secure tokens. I would paste it and it would stay greyed out and not apply the changes. I solved this by pasting the tokens and then hitting the space bar. When the value is no longer greyed out then you know it has been applied. I would also be sure to set a filter to something which you know will generate lots of twitter data. Maybe something like #trump #clinton or something.
