The balabolka tts softwae gives an error msg when using non english voices

I use and have been using Balabolka TTS, for a couple of years now as it produces mp3 files of the speech. After some time of not using the French and Chinese voice, I used them and when I did got an error msg, SAPI Error Code 0x8004503a. English voices work ok just the French and Chinese give this error.
