I can't seem to stream?

I can stream league of legends normally with the normal league client & but for some reason I can't stream the alpha can anyone help me? I'm using OBS, not sure where to post this at so.. Riots FAQ says we are allowed to stream it so o.0 it says [LeagueClientUX]: League Client ?? like i said it switches over to when im in loading screen & in game but not the actual out of game yet.. the actual 'alpha client' can someone help me please? thanks xx
