1) Uploads go to wp-content/uploads and not to the dlm_uploads subdirectory.
2) File browser injects a physical file path to where you should use urls.
3) Can't get multiple versions to work. Only works if one version per download. To advance version you must make a completely new download. Adding a new file version results in "No paths defined". Deleting the old one does not help.
4) Very limited documentation.
