I appreciate the quick and varied responses. Thanks to all. I have a couple of updates now. After work today, I stopped by RadioShack and picked up a cleaning CD. This is my experience with it:

I took it back out when the instructions told me to, put in a regular music CD, and got ERROR-02 again. I put in and took out the CCD about 10-12 more times (getting ERROR-02 each time) before it once again worked and I heard the music
