Update-I finally got this script working,warning to all users.It seems this script will not work on windows servers.I tried installing it on my server space and kept getting blank pages but when moved to our new server which runs on linux it works perfectly fine.
:EDIT:Also i have a request/idea that i think would be a nice added feature for future released.
It should have a sort of import option.for example say you have already uploaded a folder of JPG's to your server and want to add them into this download manager.It should allow you to bulk import all files from that folder into your download manager listing.Would be really nice
