I'm not sure what I'm doing wrong but I can't seem to get EOF to save tone changes. I've already tried looking at countless tutorials and troubleshooting guides but I still haven't been able to fix it. I'm not sure exactly what I'm doing wrong but I feel like EOF is suppose to save an XML file with the tone changes but all I get is an eof save file.

 

Is this my problem or am I doing something else wrong?

Turns out I was able to fix it by using my laptop instead. I haven't found out what the problem is but it seems EOF doesn't like to work on my main computer

When a tone change fails, remove the arrangement and add it again. It usually fixes the problem. It's often caused by spelling errors or the wrong tones selected in the toolkit.

If you're not getting XML files when you save, make sure the Rocksmith export (File>Preferences>Import/Export) preference is enabled.  It is enabled by default, so unless you'd disabled it, the next thing to check is that you have at least one note in a pro guitar/bass arrangement otherwise no XML file will be written for it.
