Updated and now have problems

WordPress version: 4.0
Plugin version: Pro 3.0
Link to my site: https://www.cuemusic.com

I expected the plugin to do this:
My download button to work (it did this earlier)
To be able to add playlists with shortcode (I could do this earlier)

Instead it did this:
My download button does not work anymore
I had entered duration of each track – that info is now gone
Cannot add new playlists with shortcode

Here’s what I’ve tried so far:
Nothing – do not know what to do

I can IM login details if you need.
