Earlier today i had to uninstall baldurs gate so i saved my savegame i had i NEJ and then i reinstalled everything and put in my savegame folder. When i logged in and chatting with anyone that relates to NEJ wrong text shows... I have no idea what i am saying, but when i speak to someone else that is SOA or TOB it works fine, ohh yeah all the weapon from NEJ doesnt have a description or completely wrong one..

Is there anyone that hs any idea what the problem might be?

You need to start a new game, old saves don't work with new install order or different versions of mods.
