Okay, that error that occurs at least 22 times at that point could be stopping the rest of the addon to progress and thus breaking later functionality.
Have a look at this page that explains what the UnityPowerType function returns and how to handle a non existent powerType which is what the error is reporting. If you look at that line of code and those around it you should be able to make the necessary changes.
Hopefully once that happens it will work, but possibly it will trigger the next block of errors. Work through then as they appear. Google the command and see if there is an updated blizzard file containing its use and/or the wowpedia site to see if it is updated.
Unfortunately there are so many changes to do with Spells and Maps that remembering individual ones is hard to do, unless you come across them.
