Most likely there are no more working profiles, since the shattering.
That and GB looks very bottish on a non-flying mount.
I tried to get my mining and herbalism up before the patch with GB and quickly went to doing it manually.
If anybody sees you riding around like that on a ground mount (moving backwards, etc) you'll be banned in a heartbeat.
So if I were you I would either wait till you can fly in azeroth or do it by hand.
My personal opinion..
