The files for .tif and .mp3 are in the original folder but the .txt file isn't. I tried several times and you can see the Omeka entry is fine but nothing displays because the .txt file isn't there. 
I did make a screen shot but I don't see where to put a graphic here so maybe that's not allowed. Here's the system info:

What I would love is to read up on how to enter just plain text items. I could put the text in the Description section of DC but I don't think that's the proper way. I'm so new that I will appreciate any tutorials and help!
