Can only play cached music

[BreadleyM]

Recently I've found that I can only play cached music from the iPhone application. I'm also unable to get songs from the folders to load from my Mac computer. Anyone ever had this issue before? I stay updated with the latest versions of the app and my other friend who uses the same server isn't experiencing the same problems.

Thanks!

And these are the error messages I'm getting when I try to play:
