Couple of questions mixvibe 7.21 & other

Hi,
let's start off with this one.
question 1
I downloaded DVS 7.21 yesterday and now is the case that if I go
to the download section I'm asked for my serial number,
is it because I've updated mixvibes?
I have looked in my profile but my serial number is still there.
question 2
when I worked with mixvibes 7.00 (?) I could open documents and
drag my songs directly into mixvibes.
now I have updated to 7.21 I have to use the mixvibes browser,
I can't drag my songs directly from anywhere into mixvibes anymore.
The behaviour of mixvibes has really improved with this update,
but I'm disappointed I can't work the way I did before.
I looked into preferences but I can't find anything on this subject.
Can anybody help me with this one please?
