I had similar problems after updating the translation by myself.. long story short the footlocker is a leftover from an addon mod that's usually present in Foxx's release, if you screwed up something, than Your best bet is to start saying what you did exactly to update, because ppl here are unaware what you've screwed up, and if they don't know what's wrong they won't be able to help you..
So Foxx is right..
anyways not only the translation has to be present in mods folder and the patch000.dat=1 must be present in mods_order.ini but also there's a certain other .dat file that not only has to be present in mods folder, and mods_order.ini but also has to have higher priority than patch000.dat (meaning it has to be below patch000.dat in mods_order.ini) or was it two .dat files... anyways the dat file with bookseller mod and the english translation of bookseller mod have to be present and the english translation of bookseller mod has to have higher proprity over translation.. only then the mod will be usable.. don't ask me how the file was named as I forgot how it was named, since I haven't played in a while.. I was busy recently doing some handywork for Fo:Yesterday project regarding my specialisation field in this modding community, some NDA stuff so don't ask
