I'm having the same problem as wildblue I check AV / FW if both are okay, then ran patcher as admin and that didn't work Also just tryed running 3DX chat shortcut without patcher I followed these steps: Uninstall 3DXChat Open Registry Editor Go in the Registry Editor to "HKEY_CURRENT_USER/Software/SexGameDevil right click to this Folder and delete. Close the Registry Editor Download and install fresh copy of 3DX Chat and that didn't work either. Tried Installing to different HDD/SSD or different file path and nothing.
