I also had that problem. I am running Windows 7 x64 and did not install the patch. For me, I had to navigate to the program files (x64) directory, then to Phoenix Online, then The Silver Lining. From there, I right clicked TSLconfig.exe and ran as administrator. That seems to have fixed the problem. When I ran the game, I also ran it as administrator just to prevent any future problems. Hope this helps. =)
