I've tried re-extracting rphtiny but I still get the issue, and the config is as it should be. I can reboot my computer and be able to log on within a few minutes of it booting, but after that, I get the DC issue.
There's very little installed on this computer due to it being a fresh install of Windows 7, since I've been bugfixing and shit. Only got a few games, drivers, and stuff like the Bnet launcher, discord, steam, etc.
Because I can launch within a few minutes of a reboot, it leads me to believe something in my own settings somewhere on my computer is blocking it, but I've looked through all security and firewall settings, and even the list of open processes, but none of them should be a culprit.
