"path/to/music is not a valid path"

Ubuntu often fails to mount my network drives(where my music is). If I forget to manually mount the drives prior to opening Songbird, Songbird can't find the music(obviously). However, when I mount the drives and try to submit the path into Songbird again, it states "/path/to/music is not a valid path" and I have to force Songbird closed because it won't let me close the config panel unless I enter a path that it likes. I opened the folder and played music from it in Rythmbox to make sure it was working correctly. I've restarted the computer and Songbird, but the problem persists.

How do I get Songbird to see my music again?
