Guild Wars 2

I use TP this morning, it is very slow until now,
When I clock one item, it will not display the list instantly,
I need to wait more than 3 seconds, sometimes it will show nothing.
if I want to order or buy something, it will be delayed more than 3 second,
And sometimes it never works.

Could anyone help to solve this issue ?
I’ve tried to restart my computer, but it didn’t work.

Thanks.

I’d like to change my Authenticator E-Mail address.
I can’t find this option in “My account”,
How do I change the Authenticator E-Mail address ?

Thanks

Also bugged, spend more than 3K karma, but still not get this achivement
