So I've published a demo game I'm working on....it includes the Mp3Adv script/dll for playing mp3s....when I run the resulting .exe file, I get an error about "can't open mp3Adv.wdl - script modified"...(all the files used in the game have been copied to the publish directory, so it's not a case of the file being missing)...
You may not change (and even not overwrite with a similar file) any script files. All script files must be in the "published folder", if you copy them into that folder after you have published, it might not work.
