I wish that I could be of more help. I might be wrong but off of the top of my head, it's probably a corrupted file or configuration that is left behind when you uninstall the game, that's why when you uninstall and reinstall the game it doesn't fix anything. What I would do is uninstall vintage story, find and delete all files that are left behind, and reinstall. I wish I could tell you which files or where they are but hopefully you can get it to work. Good luck.
