Q:
Guild Bank/ Build queue not showing up
If this is persistent it sounds like you are having problems connecting to the guild server. Perhaps something is blocking it.
If you open Resource Monitor while GW2 is running you should see 3 TCP connections for GW2. It might take ~30s for all 3 to show up.
If you are playing on a EU server two of the connections should have a remote address of 206.127.* and one 64.25.*
if you are playing on a NA server all three should be 64.25.*
