sorry, im not sure if this is the right place to put it, but many people seem to have problems playing trickster on Windows 7, so i found a solution to it
1.download the fix gameguard from here GameGuard
2.delete the gameguard folder and the gameguard.des file in your trickster folder.
3.extract Zip file in trickster folder, delete the extra notepad if you wanted to
then open it as windows xp with admin rights
