Guild Wars 2

I’ve just purchased the Grandmaster’s Training Manual for thief at leve 63 (3 above the required level). I’m sitting here double clicking it like instructed and nothing is happening. No trait reset or unlock and the book continues to just sit there in my inventory. I’ve also tried right click -> use with the same results.

Any help with this would be greatly appreciated. I spent all my gold on it :(

Did you buy the lvl 40 one first? You can’t skip books, have to buy them all.

Thankyou. This is the problem.
