Guild Wars 2

So I’ve logged into GW2 every day for months and played with no issues. I’m home from work now like every other day this week and upon opening the client, I can select ‘log in’ then I can select ‘play’ then the GW2 icon displays on my hotbar and no client window opens.

Any thoughts on what’s going on?

Could be several things. I would try the following before starting the game.

Delete the file C:\Users\<username>\Documents\Guild Wars 2\local.dat
Then run the game with the -repair option.
