SWYH always crashing



I’m trying to use SWYH for its http streaming function, because the audio jack from my desktop computer is broken, but I could hear the sound from my laptop.

However, no matter what I try it just insists with this same crash: http://www.streamwhatyouhear.com/forums/topic/swyh-v1-3-crashes/

I don’t think I can find alternative software either. What can I do to fix this issue? Thank you!
