I just got a new computer and uploaded Twine 2.2.1. When I try to import stories I wrote with Twine 2.2.1 on my old computer using Twine's "import from file" button, the stories appear in my library. But if I close the Twine program, they disappear when I reopen. In addition, none of the changes that I make to the stories are saved. If I create new stories in Twine, the same thing happens: they vanish from my library when I close the Twine program and they don't appear to be saved anywhere. Does anyone have any idea what's going on? Thanks!
