Forgot VLC Player passcode, what now?

[Volpey]

hey guys, i used to watch some shows via VLC player on my iPhone 6 a few months ago, stopped for a month and now i wanted to continue.
i completely forgot that i put a passcode on VLC player, and of course i completely forgot what that passcode was.
i tried reinstalling the app, but it's still there.
what can i do?
thanks in advance!
