I am building an mp3 download site and have run into a problem. So far I have 20 Albums set up as 20 Products. Each Album has a set of preview tracks for customers to play. These 25 second mp3 preview tracks are all located in individual directories within the "media" directory and all work just fine.

Today I added another 5 Albums/Products (there are many more to add) .

When I "Assign Media Collection to Product" on the 21st product the media clips failed to show in the media collection for that particular product even though the product was in the same "product-music" category.

I went on to try to "Assign Media Collection to Product" for the next four products but the media manager Assign Media box shows a another one of the recently added and previously assigned 4 Products.

Is there a restriction on the number of assigned files?
