weird bug after drizzt mod (item can not be removed )

ok this is my 2nd run of the drizzt saga in bg 1 . in the first i didnt had this problem ....

ok this this it whats happenning :  

 after finishing the saga i wanna kick drizzt out of my party ..he leaves an takes his companion with him ..so long so good...

but everytime,  no matter who i talk to ( regis bruenor etc )  drizzt puts 1 invisible item in my inventory when he leaves the group .  i can right click it . its one of his scmitars. but i can not remove it.

ok this wouldn be such a big problem but when i have that  invisible unmovable item in my inventory i cant loot  important q items out of chests for example .  just nothing happens. i could loot with other chars but im doing a solo run soooo this is pretty bad for me .

well i heard u can edit save games with nearinfinity but when i click on nearinfinity.jar  nothing happens too.........damn

if anyone got an idea what i could to  that would be awesome ...thx for the help guys and btw this forum is awesome helped me so many times i hope again ;D

ok near infinity didnt worked but then i heard about the gatekeeper 

i found my save game and was able to delete that item out of my inventory ....now everythings works again .....kinda proud of myself ;D
