JK crashes every time I try to join session

[SonicWeaver]

Until last night I have had no major issues with JK and have used it for several months. Last night I lost lost my audio in the middle of a session. I could hear the other player but not myself. After trying to re-connect several times it started cra$ng every time I tried to join a session. I uninstalled the app and re-installed with the same result. At this point it crashes every time I try to create a session or attempt to join one. 

I have not changed anything and my interface works fine. Any ideas? running 1.0.3834 on 64-bit Windows machine.
