Howdy all, new with a baffling question

Well see I downloaded the VCast Song Id app and as I try out for the first time, it says "Out of file space. Delete some files. Restart app & try again." I have no idea what it's referring to. Can I get some help

I'm having the same problem when trying to use VCast Song ID:  "Out of Filespace.  Delete some files.  Restart app & try again"

My phone memory is 51.52MB avail out of 100MB total.

My card memory is 1.46GB avail out of 1.85GB.

I think part of my problem may be because I saved the app to my card.  I can still access it, but I get that error message.  I've tried taking out the card and re-downloading the app, but that doesn't work.  I don't know how to remove the app.  I'm just kind of at a loss.

This phone can be a bit confusing so I may be totally missing something.  I'm going to post this on the Verizon boards as well to see if I can figure this out.
