Thanks for being so quick, anyway I will repurchase it right after the refund, I use Norton Security as my antivirus, but it was also being blocked by the Windows antivirus, what I did to fix it was to download it from steam, this skipped me a problem, but when I started it it kept giving me an unofficial signature warning, I confirmed it anyway, but the software would close, so I put it in exceptions and it worked, while these steps didn't work for the drm-free version
