Hi, welcome to the forum!
To prevent this happening in the future, just use MusicBee to move or rename the file. (You can edit the filename in the tag editor, or you can use Send To > Folder in the context menu.)
If you link to a last.fm account, it can save the play counts for you. It's not perfect, because the track has to match the song in last.fm, but it gets most of them. You'll also be starting from 0 at last.fm, so you'll lose what you currently have.
