Have You Any Knowledge of Bugs in Flash Player 10?

I have custom software that was developed for me by a Flash animator using Flash Player 8. Everything was working fine. It also worked on Flash Player 9. Now there is a part of the website that doesn't work. I checked with my animator and he says that the problem is a bug in Flash Player 10. He said that he found mention of it on Adobe.( https://bugs.adobe.com/jira/browse/FP-1028). He says that the remedy that they suggest is to transfer everything from Actionscript 2 to Actionscript 3. That would cost me about $2500. I am just launching this website and don't have $25 let alone $2500 to fix this issue and yet the sound is critical in this section.

Here's what doesn't work. There is a section where the kids click and drag  "pieces" and put them into photographs and when they release the pieces, they makes a sound. For example, click and drag a chick and put it into the photo and when it is released, it peeps. It doesn't do that now.

Does anyone have any suggestions for me that are less expensive than the one that I already know about??

Thank you so much!
