So, for those like me who can access and log into Poxbox but have the rune trader itself not loading ever, I've found out that using a VPN allows me to properly load the site. I'm not posting any links as I'm not sure if it would be ok( or legal), so I'll just tell anyone who might have the same problem to google "openvpn", it will lead you to the only free(ish) VPN server I have found. So far it seems reliable and fast to me - and I suggest only using it for trading with PB as it does have a data limit.
