I wasn't aware they were old versions. How can you tell they are old? Also, could you link the newer versions please?
FOOK2 v1-2 Open Beta by FOOK Team, how I know that you are using FOOK2 1.0 RC is that you have several old FOOK2 plugins that are no longer used in FOOK2 1.2 Open Beta.
DarNified UI F3, how I know that it is an old version is that "DUIF3Extras.esp" is no longer used in DUI F3 Alpha 11.
Fellout is integrated in FOOK2 1.2 OB, but if you want darker nights load "Fellout-Full.esp" after the FOOK2 plugins. The Fellout DLC plugins are fully integrated in FOOK2 and are no longer needed.
