Twinsen, to explain you audio problem.... when ever you run winamp by itself when you close it is saves all of the settings such as volume. I had the volume problem too but i ran it alone and changed the settings now it is all good.
As for your crashing, i am having the same problem. I believe i have narrowed it down to the gps. Its very inconsistent though. Sometimes it works others rr crashes over and over. As a temp fix open iguidance and winamp THEN open rr and see if that works. If you are still crashing start messing with xport. Like i said it is very inconsistent and im trying to figure it out.
