Ah I see, so is this a mod issue or is this a personal game issue? I'm playing a Seraph so I hope that doesn't have anything to do with it.

I'm exactly sure what you mean by your question. Those errors do not indicate an installation problem, but that does not mean that you don't have one. Given the number of problems discovered in Deviants code, I am inclined to say that it is a mod issue from hastily including his code.
Not enough information has been provided to determine whether playing as a Seraph is related. I have not looked at enough of the mod to know for certain, but your actions are more likely to related to the error than your race.
