Missing song folders

[shenjoku]

A lot of my song folders aren't being loaded for some reason. I've tried reload songs/courses multiple times and renaming the folders to make the caching pick it up but it never works. Any ideas what would cause such weirdness?

It might have something to do with the fact that my Songs folder is a junction to a folder on a different drive, but I had the same setup on a different computer and it was just fine.

EDIT: Never mind, I figured it out. Somehow the .sm files in a bunch of random folders got badly corrupted. No idea what happened, but I had to just delete them all and redownload nearly everything. All better now.

you need have to set Hidden songs options in OFF
That Option its available on Advanced Options but if you can't display japanese songs you need change your region settings to japan.
And that solve the problem.
