Guild Wars 2

Isn’t working.

When you ‘use’ the item it makes a three part clicking noise and will not consume. Both the level 11 manual and the level 40 manual have been used.

Game and computer were both rebooted.

Both double clicking the tome and selecting use will not cause the tome to trigger.

Anyone else having this issue?

Try resetting your traits. Maybe you already can get 30 points into one line.

Was just ~5 thread below this:

I had it with my guardian and reported it. She was level 61 when that happened and they eventually activated it for me. It just happened that my guardian was Sylvari and I bought it from outside of Hoelbrak. I never had a problem if I bought it in my race’s region or in Lion’s Arch.
