I went to radioshack to buy this Gigaware USB Stereo Headset. It said it comes with a Skype CD. I plugged the USB device into my laptop andit said "___ Has been found" and "____ Installed and ready to use!". I could hear myself talk and make noises. I connected an audio chat with my friends through both AIM and MSN. I could hear them talk and they can't hear me. What's up with that? Where's the Skype Included CD? Help please!
