DBC Edit Problem

[massflavour]

Whenever I try to save a .dbc file with an edit for my Ornate Adamantium Breastplate (into a Breatplate of Wrath), my dbc editor crashes and doesn't allow the change, but I seem to be able to do any other piece of armor fine.
If someone could please do the edit for me, or explain how I should go about doing this, that would be muchly appreciated. Thank you.
