The addon seems to be broken due to api changes in Blender, either use the addons bug tracker or try an older version of Blender that is compatible. According to the video tutorials version 2.66 was used. 

Export error with addon
In the scriptures, a phrase such as "in the name of the Lord" or "in the name of Jesus" is typically used at the beginning of statements, especially commands. In our day, I notice that most of our prayers, for instance, end "in Jesus' name" or "in the name of Jesus Christ." By way of another example, it seems that even most special Priesthood blessings by Latter-day Saints end with such a phrase, instead of starting with it.

Is there significance in the reversal of the placement of this phrase? Does the meaning change whether at the beginning or end?

(Sometimes I think when we say a prayer and end it with that phrase, it tends to get lost behind the other words, or is said quickly as a part of just ending the prayer, instead of carrying the meaning of praying in the Lord's name, which is why I'm asking this question.)
