"[HELP] adding new npc error"

Hello RZ ,
I was going to add 2 new npc i have used this guide : " http://forum.ragezone.com/f722/npc-q...-u-npc-848973/ " and it works fine for the first npc i have added it perfectly in DB and client too and it works perfectly too no crashs no thing its just normal.

about the second npc i have added it on DB and the files started normaly with no error, and i have added the new lines in client side the client crash while loading to start everytime i import " refmappingshopwithtab " and " refmappingshopgroup " with the new npc lines in it , if i remove the new npc lines from this 2 files and imported it to media.pk2 the client start normally but the npc wont have any group or tabs in it.

and i have tried to add new groups and tabs in the first npc to check about " refmappingshopwithtab " and " refmappingshopgroup " if there r something wrong in it but it worked fine and the new groups and tabs appeared in the first npc with no error or crashes
so why the client crashes everytime i import " refmappingshopwithtab " and " refmappingshopgroup " in the client for the second npc and when i remove the new npc lines from it the client doesn't crash.:?:

and also i have tried the manual way to add npc using this guide : " http://forum.ragezone.com/f723/add-n...m-npcs-815641/ " and i got the same error, first npc works fine at all , the second npc crash again when i add new npc lines in " refmappingshopwithtab " and " refmappingshopgroup ".

Thank you!
