Authentication failed / Failed to hook client

Hey, I'm new here! Just got a month and wanted to get started, but I keep getting this error;



2:38:53 PM: ArcheBuddy BETA. Version 1.2.1.0

2:39:05 PM: Game Client detected

2:39:06 PM: Authentication failed! Check is your Buddy Auth keys valid and check your sessions.



EDIT: Reinstalled and it fixed itself. However, now I'm getting;



2:51:33 PM: Failed to hook client

2:51:53 PM: Client initialization timeout!



EDIT: After a simple restart the Authentication failed problem is back!
