Training: paid trainer for a pattern but it's not in my list

[monkeybrew]

Went to train "Dark Leather Boots" at the Ironforge Leatherworking trainer. Pattern was green and trainable, I paid for it, it took my 5s85c, but did not actually train the pattern. Not certain that I clicked it the first time, I did it again and lost the money again before realizing what was happening. I lost 11s70c out of the deal and still do not have the pattern. Now I'm afraid to try it again lest I get ripped off yet again.

I've searched through the support area but didn't see a fix for this - any easy way to overcome this issue?

Thanks.

Greetings,

close your game client, delete your WDB folder and then try again. That fixes the issue. We do not reimburse you for the money lost.
