Error creating playlist folder

[Flordeneu]

When I try to create a playlist folder, it gives me this error:

Do you have any idea about it? Thank you!

the error doesnt help and i cannot reproduce any issues, so can you provide a step-by-step guide for what you are doing

[Flordeneu]

I'm not doing anything strange. I just click: MusicBee menu -> File -> Playlists -> New Playlist folder

Then, instead of creating the folder, I get the error message window with the error above. It used to work, but it doesn't now. I uninstalled the program, re-installed the latest version and I still get the error.

Stranger still, I just found out that if I click on the right mouse button on the playlist window and select New -> New Folder, the new folder is created without a problem. However, if I use the menu, I still get the same error.

[Steven]

when you use the main menu, what is the active node in the left navigator at the time you do it?

[Flordeneu]

The Playlist Manager.

[Steven]

thats fixed for the next v3 patch update

[Steven]

unzip into the folder MB is installed:

I'm sorry, but it's only partially fixed. Now when I click on MusicBee menu -> File -> Playlists -> New Playlist folder it doesn't gives me an error, but the folder does not appear in the playlist manager either. I have to close the program and re-start it to see the new folder on the list.

redownload the same link

I'm sorry, but it's not fixed yet.I still need to close and re-start the program to see the new folders created
