Hi @Krikor

thanks for sending the crashlog, we will have a look.  
The next update is in two weeks and will contain many stability improvements.

In the meantime, it seems disabling the audio detection can help, working at a lower samplerate has been reported helpful as well if you were using anything over 48K.

Cheers,  
Ed
