First sorry for my bad English

Game started with v 3.51, I installed 3 mod :
Black Market Seminars
Capital Ship Bridge
Show Skills
put all 3 two months ago with v 3.61 all 3 work (except translation Black Market Seminars )
After the update v.4.0 Black Market Seminars stopped working, I'm sure because I still have two seminars in the inventory and they are not visible from the merchants

maybe it depends on my lack of knowledge, but the files in the mod folder are different when taken by steam or nexus (old version seems to me):
Steam
content.xml
ext_01.cat
ext_01.dat
Nexus
libraries folder
wares.xml
folder md
npc_itemtrader.xml
Strudo76_BlackmarketSeminars.xml
folder t

main folder

For Strude
