No videos are queued when using Hot Folders in version 3.5.05
Version 3.5.06 fixes this issue. You can download this update from our beta download page
Note that all pre-existing Silent Hot Folders will be disabled when upgrading to this version as a new Hot Folder infrastructure introduces a new kind of Hot Folders allowing you to switch between Regular/Silent functionality on the fly.
If Hot Folders are still not functioning after upgrading to the latest version of VideoDrive, please try to run the Welcome Wizard again. It's located under Help in menu bar. After finishing the Welcome Wizard successfully, Hot Folder functionality should be restored.
