Can not drag and drop new tracks from my drive in to my rekordbox collection.

This was working fine until I reinstalled my OS, now when I try to drop a track into the collection from my music folder, to import and analyze it, there is just a stop symbol, I have tried to reinstall it without any change.

I'm using Rekordbox 5.6.0 , windows 10 64bit

I tried to download the 5.6.1 beta4 but there are no longer any download links available in the forum post.

Please help.
