This is a strange one and has been happening the last couple of betas - I wasn't sure what was happening but now I've got the details worked out.
When downloading something - I never checked if they had downloaded until a couple of days after. When I would go to the folder the folders for the would be there but they would be empty - no songs.
Today I experimented and downloaded a and checked the download folder and the songs were there - good. I just went back to the folder to play the and the folder was empty again. The only thing I have done since checking the folder after downloading, was to shut NBpro down.
I presume NBpro must be deleting the files when it shuts down - weird!!!


All NBpro downloads go to a seperate hard drive in the PC I just use for storage.
