The problem with the music mod

[VovaFreeman]

Working on this guide http://forums.kleientertainment.com/topic/28108-music-mod-tutorial/ , I created musical events and decided to check it out in the game. As soon as I start the game, I get a warning window modes (as always), but when I take it off the game, referring to the error. But when I remove all the mods, this problem disappears. Maybe somebody knows how to solve it and check normal modes?
