I've been a happy player of the original Sins that I purchased over a year ago. Today I decided to upgrade the latest version, so I installed impulse and downloaded the latest update. After rebooting, however, I am unable to start the game. The 'Sins Launcher" starts, but just sits there with nothing displayed on the screen and taking no CPU time. I can exit the launcher by right clicking on its icon in the task bar, and attempt to relaunch it, but it just does the same thing. Just sits there with no window displayed. I'm running Windows XP with an nVidia GTX 280 graphics card, Intel Q6600 processor and 4 Gb RAM. I'm going to try uninstalling, and hopefully re-installing
