Audio files not working

Again !!!  I've had to redo so many worksheets over the past couple of months.

Today morning, I found (yet again) that audio files aren't working on worksheets 2176672, 2175821, 2175792, 2175779, 2175758, 2169177.  I can keep going on and on with more worksheet numbers.

Please help fix the issue soon.  This is proving to be a huge handicap and worksheets remain pending.

I moved to a paid account with the school's approval this year and now they are beginning to question as to why pay for a platform that has so many bugs and hitches.  I have no answer to that.
