Perhaps she placed some files in the wrong folders? It is quite easy to make a few mistakes while installing maps, especially if there are custom objects and textures in it.. which by reading the log I can tell you used a few objects not already provided in the game itself. Try aiding her when downloading / installing the map if that is the case.
If she knows how to install maps already and mistakes seem out of the question, then it could possibly be the game itself that is having issues. A few files are corrupt, as I can see from the log. Tell her to delete the game as well as the main folder, and completely reinstall it again. This should fix the problem. ~
