Hello, awesome piece of software. I used it once with strangers in the public jams and it worked great. However I am unable to do my own jam. I am trying right now with my friend in the other room and it's not working for some reason. Can somebody help me?

Here's the log:

No1 For a start try posting Problems in the Technical support part of the forum!!!
No2. you clearly have setup you Go Mic as an output device as far as im aware microphones are input devices.

Hope this helps..

The log file suggests that the GoMic wasn't plugged in when jammr was launched. jammr will not detect audio devices that are unplugged/plugged while it is running.

Please connect any USB audio devices before launching jammr and check the audio settings again before connecting to a jam session.

Hope this helps!
