The vive index seems to have some issues at the moment. We're looking into it, but don't have an index ourselves to test with. Feel free to hop on our discord server to discuss it.
If you'd like a refund at some point do let me know, I will ensure you aren't stuck with a game you can't play. We'll do our best to get full functionality for the index as soon as possible, though.
The demo IS the full game. The purchased version is also the full game with a bunch of extras. There is no bug I'm aware of causing anyone to go back to the main menu. If this is happening to you then you should show what's happening so we can try to fix it.
