Hello, after the changeover, I can't find anything anymore, and I don't understand the whole system at all. Please help urgently. I actually created five projects, and because I wanted to create a new project, I deleted one, but now I still can't create a new project. Then it's the case that five out of five songs are currently selected, but I can't reduce this number. What am I doing wrong? Can I export this data before deleting the projects? And then there's the question of how the whole thing works automatically. Or do I have to purchase Standard and Premium Submissions for each project? Please help!
