Hi Raddy,

I'm wondering which version and build you're running. You can find out by clicking Help, then About Band-in-a-Box.

I'm sure you're using something older than 2018, but may need to install the latest update for whichever one you are using, as you should be getting a "Driver cannot do the requested conversion" when trying to make MP3s without a codec installed, not a crash.

You can get update patches here:
