Problem with Roger wilco settings

This was working....I noticed my rear speakers were not working, don't know what happened. I d/l the sblive software from creative. No problem, done it a hundred times. All is well with sound and speakers now. But when I went to fly on vatsim, I noticed that now everything I say into the mic is coming over the speakers. I never was like that. RW still works when I key it up. It's very annoying to hear myself breath. I tried to mute the mike as suggested at the RW web site, but when I do that the mic no longer works. I wish I could remember how it was set up, but I can't. Any suggestions?
