I just installed Studio One 3 on my MacBook Pro with OS X 10.11. I downloaded all updates and installed them. The only download I cannot install is the Tutorials & Demos. I have it downloaded but when I hit install it says: Studio One - 1 of 1 packages already exist on your system. - Studio One Demos and Tutorials. - Do you want to install the missing packages only? - Three buttons say install all - cancel and Install Missing. What am I doing wrong?
