Can't add products in Media Manager

For some strange reason, I have six products in my CD's category, but my media manager keeps saying that there are no products in the category every time that I try to assign a media collection to a product!
And do I have to have a little media player on each of the pages in order for my customers to preview the music, or does Zen Cart do that automatically?:dontgetit:(
and I do have the new version of Zen Cart

For some strange reason, I have six products in my CD's category, but my media manager keeps saying that there are no products in the category every time that I try to assign a media collection to a product!In v1.3.8 and earlier, there is a small bug that causes that message to appear if you have only ONE category in your database. The simplest way to work around it is to add another category (even if you never put any products in it). Then when you open the Media Manager screen, use the pulldown menu to select the dummy category, and then select your "real" category ... and then any music products in that category will appear properly.
This bug is fixed in the upcoming v1.3.9 and newer versions.
