I finished tabbing a song in editor on fire and the first 15 seconds of the song work in Rocksmith. But after that no more chords or notes come. Help!

Is it possible you used a preview audio file with the toolkit instead of the file for the full length song?

That could be because there was already a xml file i just used that because i thought it automatically made one. So how do i export my project to an xml file?

If you have the "Save separate Rocksmith 2 files" option enabled in File>Preferences, EOF will create an XML file for each guitar/bass arrangement when you save the project.

Thanks that did the trick! :)
