I just downloaded 4.8 basic version, and i tried to download some songs, but it won't even download anything.

It's like the download button is malfuctioning.
It searched fine, it's just the downloading that won't work for me.

What do i do now?

The previous versions worked fine on my computer.

What's up with that?

Did you configure your firewall so it allows LW full access (advisable not to have 2 active firewalls b/c they can interfere with each other); Firewall configuration instructions (click on link)
