Emma, I've never had any problems with Excel 202 losing audio. This class is over 4 years old now, and nobody else has complained about it. Perhaps it was a buffering issue on your PC. I would recommend rebooting and trying again.

If you're having problems understanding something in one of the lessons, just post your questions here and I'll be happy to answer them. Remember, the lessons make much more sense the SECOND time through. Watch the video ONCE through without doing anything. Then watch it a second time and follow along with my examples.
