Importing Scaler 2 chord sets into Scaler 3

I recommend the official solution already provided, but for those who are curious about possible causes, I suggest checking the link below.

David kindly took a look at the xml file of one of my exported chord sets from Scaler 2 and found that there was a structural problem in the file, which happened to be easy to fix. I was able to use the same technique myself on a couple of other files and they then imported successfully into Scaler 3.

This was a few revisions ago, but the key point I want to make is that the problem was in the Scaler 2 export, not Scaler 3, and it persisted across multiple exports of the chord set of the same project.
