I found that and apparently I have 4 articles from the 'features package' category for free. But when I try to purchase the "More tracks..." it does nothing.
What a stupid, convoluted piece of software. What I did was... I got to the option in the store where I can purchase the "More tracks and formats" and then at the top of the screen there is the little bust icon to log into the store, clicked that (even though my email already appeared beside it, which in most programs indicates I am logged in) and a new screen pops up asking for email and password. Enter that and a new pop pops up with that "More tracks and formats" feature offered at 0$ but I have to put my password in again. I'm assuming I'll have to do that with all four free features. Then there is a notice that I should wait for it to finish downloading, but no indication of progress or that it did, until I go to the FILE menu and see that the mp3 feature is now there. wow.
