For uninstall GameGuard just delete the files GameGuard.des, the folder GameGuard in your Trickster Directory and the Folder INCA Shared in C:\Progam Files\Common Files.
For reinstall just run Trickster Client (as Administrator) and GameGuard starts downloading/install the files again.
After Patching GameGuard and Trickster Client loaded complete, close it.
Start Client again (without Administrator rights, just normal start)
GameGuard will patch again! (but crashes after client starts loading)
Close Trickster after.
And last just start Trickster again (as Administrator).
This worked on my Notebook. :3
