Run the shortcut as Admin

Only client 20120627 has this issue just create a new shortcut for FEZ/ Run FeZero.exe directly from the Gamania/FantasyEarthZero folder
4.Black Screen after passing Character selectionEdit
Add the entire FantasyEarthZero folder to your antivirus's exceptions. Or at the worst of it try uninstalling your antivirus.
HKFEZ has been acting strange lately at certain times, if it doesn't work then please try launching the HKFEZ client at another time.
Frame Rate Limit ToolsEdit
The tools that require files inside the client will not work. If you want to have your FPS limited then use a video recording program like DXTory to limit your frame rate.
