the models won't export.

I have a small question:
So, I extracted a screenshot, recolored it, saved it as a TGA file, and put it in the map in UI/H5A2/Creatures/NecropolisSecondUpg/name.tga; and also in model/.../.../name.tga.
Then, I opened the map with WinRAR, found the file in model: something like DeathKnight_Coat.xdb. Inside, there are Scr_name and Dest_Name. In the first one, I wrote a long path through UI, and in the second one, I wrote name.tga directly, since it's in the same folder.
I opened the editor, checked, everything matches, the links appeared. I decided to check how it looks, selected it, and the editor crashed. What did I do wrong?
