Huh, yes, there is an error in the .d file, but that should only cause Minsc's banter with Indi not to work properly.
Do you have Infinity Explorer or NI or some other program capable of viewing scripts?
If so, can you check if the script _ar5201.bcs and see if it contains the following:
IF
GlobalLT("J#IndiSpawn","GLOBAL",1)
XPLT(Player1,20001)
!Exists("J#Indi")
THEN
RESPONSE #100
SetGlobal("J#IndiSpawn","GLOBAL",1)
CreateCreature("J#Indi01",[1012.1467],14) // Indira
END
IF
GlobalLT("J#IndiSpawn","GLOBAL",2)
XPGT(Player1,20000)
XPLT(Player1,40001)
!Exists("J#Indi")
THEN
RESPONSE #100
SetGlobal("J#IndiSpawn","GLOBAL",2)
CreateCreature("J#Indi03",[1012.1467],14) // Indira
END
IF
GlobalLT("J#IndiSpawn","GLOBAL",3)
XPGT(Player1,40000)
!Exists("J#Indi")
THEN
RESPONSE #100
SetGlobal("J#IndiSpawn","GLOBAL",3)
CreateCreature("J#Indi04",[1012.1467],14) // Indira
END
