Microphone Issues

While doing the voice acting for the first third of Bryson's Mind: Episode 1, my microphone was being really annoying, but at least it worked. I had to start recording, squeeze the cable just right, then it would actually record something more than static. But now, the microphone's absolutely shot, and no amount of cable-squeezing will make it work. I've ordered a new headset microphone from Wal-Mart, and it'll arrive in 1-2 weeks, so no voice acting until then.
