I don't know what's wrong with Novetus, or maybe I did something wrong. But when I click on Play Solo, something opens, and an error immediately appears: "Failed to open document", and the title is called "Roblox". After digging through the game files, I realized that these maps are like Roblox's own places, but I don't understand why nothing works for me! I opened these places directly, but they just opened the regular Roblox Studio, and that's it.
And I even downloaded the beta version, but it's the same. Well, except that the game opens, but also the error ID=15 appears, and that's all.
UPDATE: I decided to make my own map. The studio itself worked fine, but I couldn't save what I had built!! The map file just didn't appear! And yes, I even opened Novetus with administrator rights, but neither the prepared maps opened, nor my map was saved.
What I need to do to fix it??
