UWO doesn't start with Sandboxie installed

I haven't been able to play this game for a long time because I installed Sandboxie and GameGuard won't start because of it (insider or outside the box). I can't uninstall Sandboxie because I use it for other stuff. I hoped that things have changed but it seems everything is the same, except the fact that you wiped the hard work of everyone... I can play big games like World of Warcraft, but not this one, makes no sense. Please fix this or me and possible many others won't be able to play, thanks!
