Happy Easter to all. I just purchased 2021 pro version but I cannot find any songs .mgu, sgu files in my song folder. Maybe I should not have any?? When, I try to open a song I have a request to rebuild song list, so I do that and the program reports there are no songs in the folder. The song folder is located in my BB directory just like my Realtracks. Would appreciate anyone's help with this. I might also add that I requested a flash drive when I ordered but I also was provided links to download, which I have completed.
