Disconnect from PvP when selecting the Crafting Tab

Hi all,

I am having a problem when selecting the crafting page - I get disconnected from PvP .net, and it doesn't reconnect.

Attempting to log back in, it gets stuck at "logging in ....".

The only thing that fixes it, is a reboot. I've even tried closing all processes, to no avail.

Has anyone else come across this?

It first occurred directly after purchasing a key.
