Resource types

Hi Mary! OK...I've got the files in the file system repository and they show up in file picker. However, they won't load in any of the traditional manners. I can get them to load and play from a folder other than uploaddata but then you can directly access them from the outside if you know the link. Here's the kicker...I did one test back in the spring and it works. I do one now with a file put in the same folder and it won't work. Any ideas???  (they don't have a smily pulling their hair out....)
