Hi hi I have seen another forum that addressed this issue however, I have tried all the suggested fixes and nothing has worked for me. The compatibility has been changed to windows 7, I've allowed the SBLauncher.exe, SB.exe and Xigncode app as exceptions through the firewall manually. None of these options have worked for me unfortunately. Are there other things I'm missing or something else I could try? I have also tried re-installing the game files, that hasn't worked either. And yes, no error message comes up at all. After the circle beside my mouse that signifies loading is finished, nothing happens.
