so, i had to reinstall my OB (corrupt data, blah blah blah) and then i reinstalled it, all the mods work fine except the 2 replacers i use, mythic creatures and a map replacer.

i had them installed fine before, but now when i copy the files over to the appropriate files they dont seem to be "replacing".

i've tried everything, anyone know whats going on? other mods are working fine!

Archive Invalidation with OBMM should do the trick.

oops, forgot to check this! what am i meant to do with the archive invalidation thing? all the settings area bit confusing for me!

Just click "Archive Invalidate" under the BSA tab I believe. Close OBMM and run Oblivion again. Your textures replacements should be active again.

when i press it another window appears, a very confusing one! what do i do?

BSA redirection is the safest and most stable variant, so:

Utilities > Archive invalidation > BSA redirection > Update now

Some texture packs have a screenshot that shows what settings are needed to be set for the textures to be shown ingame. It always works for me so you can go to Utilities > Archive invalidation and then use these settings:
