Guild Wars 2

Scout Acon in the personal story will not talk to me. I have glided up to him and the story has continued for me to talk to him but I cannot, he just keeps singing on his guitar

I tried leaving the map and coming back and he still won’t talk to me no matter what I do.

So since that last update I have had a problem with server connection during the game. (still working on my end to find the problem) The game connection has gotten so bad it has completely kicked me out of Guild Wars 2 and back to my desktop. After this happened I started getting a message every time I click on the application icon to load the game (image attached) Going on your forum I found the link to fix the application in the terminal, it does work but I have to do every time I want to open the application. I have tried reinstalling the game but that doesn’t seem to work. I have the Mac version of the game. is there anything that can be done?
