Gatherer / Gatherer Mate not working for adamantite ore

Hello guys,

I'm farming with Gatherer and I recently noticed that it doesn't highlight any adamantite ore I finde. Now I installed Gatherer Mate 2, same result.
Does anybody know how to fix that or what's wrong?

Thanks in advance!

Are you sure you downloaded TBC version?

Try this one from one of the addon posts on Lordaeron. It's for 2.4.3 so it should work. https://drive.google.com/file/d/0B26...5mOTdjUUU/view
