Modern Player not working properly

This one is complicated and server based. Turns out that java scripts are cached on the server, separate from browser caching at the firewall/browser level. I don't understand it other than by creating a new folder on the server and uploading to that new folder, cleared the js cache, or started a new cache, either way the player problem I was having cleared up. I would upload a program, brand new, and the player would keep playing the old program. Nothing I tried would change that until I created a new folder on the server and uploaded the program to that folder.
