Reply to Snap light blinking :S / Audio streaming

Hello everyone!!

I've been posting during the last weeks but in case you don't know me yet I'm Nicolas from Chile, a happy traktor s4 owner hehe. I got my controller couple weeks ago (from DJ TECH TOOLS) and feel very happy for the service, very good customer service from Zach!

Well, I started using S4 software but as soon as I installed Traktor 2 I quit S4. Then, I started to use S4 again for no reason but then when I used Traktor 2 again I couldn't make my controller work (even audio). I noticed that "snap light" is blinking, there's no audio and I can't make it work. This is not happening in S4 software, is currently working normal there but in Traktor 2 snap ligh doesnt stop blinking. I didn't change any setup before so I have no idea what's happening.

Anyone could help me?
Also, one more question:

Is it possible to stream via Twitcam/Ustream using my S4 audio card? Sending direct line to the website. I have only my controller, no external audio cards. Actually, when I go to audio preferences in twitcam, it shows me traktor s4 card but when I select this there's no audio interference (volume signal doesn't even move)

I would really appreciate your help!!
Thanks

Regards from Chile,
Nicolas.
