You guys are lifesavers! I purposefully have my arcade computer offline to avoid Windows updates because I figured "If it ain't broke, don't fix it." Everything had worked fine, so I let it be. Last week Windows crashed on me (stupid blue screen of death), I had no choice but to re-install Windows and any new updates that came with it. Sure enough, Hyperspin would not open. If it wasn't for this thread, I would have never figured it out. THANK YOU x1,000,000
