Thanks for the offer to help! I've uploaded a new build - WordAfterWord Windows (Debug). Could you try it?
After running it, it should produce a file called "output-log.txt." If you could email me the contents of that file, it would be much appreciated. My first name at playfulsystems dot com.
The error I found was pretty deep in an old library that is no longer being updated. Hopefully I can debug this. If not, I might have to pull the game for the time being.
Thanks again.
