I bought The Logitech G430 Gaming Headset about a year ago. Today when I went to play Civilization 4, I only got sound from one ear. All the settings worked fine (in the game and computer) yesterday. Please help me resolve this problem!

How are you connecting the headset to the computer? 3.5mm or USB? For the sake of this, I'm going to assume you're using the USB adapter.
You can try plugging in another set of headphones into the USB adapter to see if you still get sound. This will check to see if the USB adapter is at fault. If this works fine, then it is most likely the headset. Is the cable damaged anywhere?
