Download the "MoP old" from here: https://www.warmane.com/download and you will be fine
as you can easily understand by reading that Error message it is due to your MoP with Wod models

Actually no, there is no problem with the WoD models, that's just the exe throwing the error, if you read you can see this is the cause for the error :

A texture (inside Orgrimmar (or SOO ?))

Have you downloaded the full client? (Is the torrent saying Seeding?)
