For some reason all files with the .song extension will no longer load if you click on the .song icon. The Studio One icon would be visible prior on all the files, and now there is just a icon that looks like a blank piece of paper. This is present on all .song files, original files, the backup copies, Dropbox, everything. Please help, I can no longer go to saved files, and click on the Studio One icon, and have the file just open up in Studio One. When I click on the icon, I get a message that asks "which app do you wish to open it with" and also "search for in app store". I have no idea what happened, or how all the file associations have changed. Please help in this regard, I can no longer open up saved files from years ago.
