You 100% sure you meet the system requirements? Looks to me like you don't have a fast enough computer according to this picture [came from the official site].
At any rate, if I am misreading something, it does look like your computer is too slow to run Trickster, regardless. Unfortunately, for Trickster, you really do need the Recommended Specs. to actually run the game [it will run with the minimum, but it is truly horrid].
