Thanks for your reply and sorry I’ve not got round to sending the stuff.
I actually sorted it myself, but had to delete some random text that was always put in the file location line in the file line. This happens every time I export a playlist.

I export it and all the file locations are written
Twist &amp Shout Act 1/
The file should be
Twist & Shout Act 1/

The word ‘amp’ appears at this location in every export I do.

Most odd, but by deleting it and saving, it works perfectly.
