Did you read the ReadMe file? But yeah, you need to disable the Smilie Box on the side of the advanced editor in order for it to work properly. ReadMe has the path to where the setting is. If you continue to have problems, let me know.
I downdloaded today.
I wonder if I have the most updated version in my customer area
as I do not see anything in the ReadMe about disabling the Smilie Box?
Ok, I'll take the blame on that. I updated the ReadMe in 1 location, but not the other, and the download got generated from the other location. So that you don't have to download the package again, here you go...
