Protective Brace?Follow

Okay, I go to the broker to buy some spell upgrades and come across this spell, Protective Brace (Adept I), lvl 14, necro and conj spell. I buy it and the money leaves my inv but the spell never arrives. I contact a GM and they immediately put the spell back in my inv. I try to scribe and it won't scribe! I've looked and looked and nowhere in Necro or Conj spell list is this listed...

Is this a spell that went bye-bye and I just got gipped into buying it or what?

Any help would be useful.

Thanks
