CDEX Error: Can't send to external encoder

I’m trying to encode Flac with CDEX since EAC has caused physical damage to my system. The problem is CDEX gives me a constant message it can’t send the ripped audio to external encoder, in my case FLAC encoder. Any suggestions?

First, I’d take a look at all the settings. Are all files necessary where they are expected to be?

P.S.: Out of curiosity: How can a piece of software do physical damage to a computer?
