You're missing textures.

I extracted them from arcane client, but it didn't solve the problem; however, i think the problem is in the linked regions precisely in the RefRegion; the Region ID has an ID Number in the linked region 1, but this Number doesn't have a line like the Region ID that has this Number in the linked Region
I know it's a little confusing ; so here is a pic of the RefRegion

The Number In Yellow = is in the linked region 1 in the line of the number (21837)
The Numbers which are pointed to by the Green Arrows= are examples that show the numbers which are put in the linked regions, have a lines also written in the RefRegion, and that the number (21836) should have also it's line, and it should become like this

All I want is the line which i should put for the number (21836 ) in the RefRegion....And Thanks And sorry for my bad English
