Trickster is patched completely. Only Launcher fails, but it's still possible to play.
Try to start client directly, without using the launcer.
Create a batch file
Open notepad.exe (Editor) and type in this:
Save as "start trickster.bat" whereever you want, for example on the Desktop.
Run this file. ^^
Maybe your Trickster is installed on another directory or hard drive, then just change the path manually.
If GameGuard crashes, then run this file as administrator.
I hope it work for you XD
