RA4W VPN

Hello everyone,
Got a wee prob! I'm a total newbie at all this but at least I've got my MXQ Android box up and running with LibreElec ( lots of sweat & tears).
I've now installed Zomboided's VPN manager and I;ve subscribed to RA4W VPN, I've entered my login details in it and though t to myself, hmm this is too easy.
I was correct!
I haven't a clue what's happening now, I can't 'OPEN' the vpn manager or indeed use RA4WVPN.
Does anyone have any ideas, apart from me leaving things alone I know nothing avout?
Many thanks in anticipation.
