@Jarl as i said in main post, it's the disc version, steam is not involved. I just got troubled with: 1. Archive Invalidation, because if i read some guides like here: https://www.loverslab.com/topic/65195-guide-to-using-mod-organizer-with-oblivion/ or else guides on step-forum, even he is talking of an "ArchiveInvalidationInvalidated.bsa" in Archives-TAB, but I don't have a file like that. MO doesn't create that one. I only got a "Oblivion - Invalidation.bsa" in Data-TAB & in Oblivions-gamefolder. 2. OBGE 4 doesn't exist anymore. I'm using the current version 6.0 ( called Oblivion Reloaded - OBGE ) and all guides I've found ( even here on step ) are only talking about OBGE 4 and different "OblivionReloadedEsp.ini" settings. 6.0 doesn't use that. And I'm not sure about if I can install 6.0 through MO, so i can use different profiles, or if I need to setup by manual directly to Oblivions-gamefolder, because it is a plugin to OBSE ---- same questions with MenuQue which is needed for OBGE & Weather - All natural which is a OBSE-Plugin too ( well, a further question would be: what is if i got "Overwrites" in MO highlighted in red - what to do? In answer to this question there are in some forums completely contradictory statements. )
