There was recently a bundle containing VEGAS Pro and Music Maker 2021 Score Edition. I've had a lot of fun with the latter so when I saw a new bundle with a new edition and the loops and instruments that came along, I quite enthusiastically bought it. When I tried to activate it though, pretty much nothing changed : no loop, no instrument ... Heck, the store was even telling me I could buy the Hip Hop edition !
Eventually I figured out that the edition bundled in Heal: Covid-19 bundle was for Music Maker 2020 and was not compatible with the 2021 version.
Was that intentional ? Because it isn't mentioned in the item description on the site (it is in the video description but I can't ctrl+f videos). I wouldn't go as far as saying that I feel scammed but, yeah, I'm definitely disappointed.
Anyway, I hope this will save the time of other people in my case.
