Vocalise WAV or comparable component on Vista

Although Digital Curiosity does not list Vista as a supported OS, I tried to install through Flash 8. I installed the microsoft speech software as well, but I don’t think that it works on Vista. Vocalise WAV will not open and crashes Flash. I have tried to contact DC but they have not replied.

Could it be that I just need to install the correct microsoft speech software?

I need to figure out how to get it to work on Vista, or find another program that works on Vista. Flash only software. Has anyone else stumbled upon this obstacle? I am a web based training developer and we use Vocalise WAV on 75% of a 1,000 page course!

Thanks in advance!
