Missing Activation Tab

Hai, I just downloaded and installed the latest Rekordbox (ver 6, if I'm not mistaken). However, when I open the File -> Preferences window, I don't see any License activation tab. Instead of the tab that used to be right next to Advanced, there's now a tab saying 'Lighting' with an icon looking a bit like the Hubble telescope searching the sky or something (Yeah I know Hubble's flying in space, but I don't know what names the earth-bound telescopes have so please don't make a fuzz about it ok). And on the right next to that tab there's nothing, nor is the License key tab to be found anywhere left on it. So, what's up? I'm not allowed to continue my monthly subscription anymore? Rekordbox thinks my money is tainted or something??
