Alright then. So, i got the Darnified UI, and i have been hesitant, but anxious as all hell, to get Project Brazil going (Mod here: http://newvegas.nexusmods.com/mods/45138//? ) Thing is, they tell me the mod uses Revelations UI....

now, me, liking DarNified UI so far, am a little hesitant to get ANTOHER UI.... but i will in order to get Revelations UI. thing is, i don't know what to do.

So, if ANYONE got both DarNified and Revelation UI's, and used this Patch, how do i do this PROPERLY?
