Invalid path (NSMBU DX) about miyamoto HOT 2 CLOSED

Hello. For starters, you may want to update to v28.0 (unrelated to the issue, but it's a better version). v29.0 might come out in a few days. (EDIT: Looks like you edited your message to add that you tried v28.0)
Anyway, make sure the Unit folder is present next to the Course folder.

Thanks for your fast answer!

Indeed I edited my message.

I tried a few more times and it worked...

I forgot Unit folder but had an error message after the paths config.

I think it was a bug because I use Windows with Parallels Desktop on my Mac.

Thank you!
