I was trying out besweet to convert some wave files to
AC3. It was working properly until I killed a transcoding
task while it is running. Thereafter, I have been getting
the following error:

BeSweet v1.5b22 by DSPguru.
--------------------------
Error 73: Unable to get ac3enc.dll interfaces
Quiting...

Does anyone know how I can get it to work again?
I have tried cleanning up the directory where besweet
is and re-unzip the downloaded file, but it did not help.

Any suggestion will be appreciated.
