When i try to open DownloadServer.exe, it close immediatly... anyone can help me?

check ports on server.cfg and srnodedata.ini

As silly as it might sound, but it could also be the cause of your internal firewall (software like kaspersky) or external ones (hardware firewall like your router/modem). Opening ports won't help there nor do anything, if one of your beloved protections are denying fortifying data transfer on UDP style.
