I can't open any projects. I try to open one from the 'Recent projects' side menu, an error message pops up saying 'The selected project can't be found.' I've tried to click the option 'Open project,' but when I try to click one of my projects to open it opens the project folder, revealing nothing (image). I've also tried to open my projects straight from the Mine-imator folder (not the application), but I can't find the option to 'Open with [Mine-imator]'. I have the most recent version of Mine-imator and my computer is up-to-date. Thanks for any help!
