Openvpn Voxel help

Hi all, 

I have just flashed Voxel 1.0.2.59sf and have it all setup working fine apart from my VPN.

I have followed the guide and done:

1. format usb to fat32

2. created a folder called openvpn-client

3. copied my vpn *.ovpn file across (digibit)

4. edited the "auth-user-pass" line to read "auth-user-pass /etc/openvpn/config/client/auth.txt" 

5. created the auth.txt file in the same folder with the two lines of my user and pass

Now I plug it in and nothing happens, I restart and again nothing changes? I came from dd-wrt and the openvpn worked as it should.

I've tried different USB and I just can't get it to work :(
