"Invalid URI..." message when downloading playlist

[sfan]

I'm getting an error message when I try to download a playlist, saying "Invalid URI: The format of the URI could not be determined."

The playlist link below isn't the one I'm trying to download, I'm just using for this post, but the same message appears in the playlist I'm trying to download.

Hi Sfan - sorry for the delayed response.

Wow, 225 entries - was RMC able to queue up the playlist, or did you get this error right away?
