There is no such known issue but we will look into it. For now I recommend using forgot password to reset it again.
I figured out what was the problem, I had to use my username (Flodner) while with e-mail (which was saved automatically) login didn't work.
You might make available login both with username and e-mail.
On many services e-mail is username, so future users won't have similar problems
Streaming works ok, you just need more streamers and more promotion for the platform
We are working on a full release at the end of the month with all features, at which time we will do so.
