Salamanca

I'm trying to play the demo but can't get the game to launch. I get this Windows error window: EOS.exe - Application Error The application failed to initialize properly (0xc0000005). Click OK to terminate the application. I've updated to the latest version. I've uninstalled and re-downloaded the demo, with the same result. Running Windows XP, Service Pack 3. I'd be willing to skip the demo and buy the game outright, but I'm afraid I'll get the same error. Anyone else have this problem?
