After Effects FPS and audio problem?

I'm using After Effects CS4, and my video camera shoots at 60 frames per second. After Effects slowed the video down, because it was trying to play it at 30 fps. When I sped the video up to 60 fps, the audio automatically sped up to 2x faster. The video was playing fine, but the audio was ridiculously faster than the video. Did I do something wrong? Help!
