Why do i get “*Date* SIGUSR1[soft,auth-failure] received, process restarting” and cant connect?
Your VPN account is in use already, only one computer can be connected at a time.

Why do i get “Sorry, ‘Auth’ password cannot be read from a file”
Always make sure that you have the latest OpenVPN GUI Application installed, and ALWAYS run the program by Administrator. In this case – right click the OpenVPN application and select Run As Administrator.

OpenVPN on Windows 8 Routing fails
It looks like OpenVPN requires the “Network Connections” service to be running. Simply change this service from manual to automatic (so you don’t have to do this again) and start it. OpenVPN should then connect correctly with no warnings.

Open Startmenu, type services.msc press enter, look for “Network Connections”, open it. Change “Manually” into “Automatic”, enter. Now reconnect the OpenVPN connection, voila, routing works!
