ERROR: "There was an error while creating your playlist"

[armandhammer]

I keep getting "There was an error while creating your playlist. Wait a few seconds and try it again." when using the Textbox to import ISRC numbers. It completes the lookup fine, but at the bottom of the screen when I input a playlist name and click "Create Playlist" it returns this error after a few seconds. It was working fine a few hours ago.
