Buy a VPN that has openVPN or IPSec protocol for a month? Do check if they have problem with China, China had blocked access to a lot of VPNs from time to time. UBC one might have been a victim?
P.S: I just tried tracerouting to UBC's VPN IP from my VPN in China. And it's unreachable. But my home connection seems fine. So, it's probably blocked by Chinese firewall.
