Vpn Network Connectivity Lost

Hello Folks,

Here's my issue...I am deployed in Afghanistan where the price for internet is around $130, after a while I found that through a VPN (VPNunlimited) I could connect to the internet for free. Lately a new company took over the network and the next thing I know my VPN stopped connecting. Normally I'd have to establish a good connection through tethering from my phone, let the VPN connect to my Luxembourg server, then turn off tethering and then the VPN would catch the local WiFi signal.

This is no longer working, I've tried doing research and was thinking that perhaps if I route the traffic through port 80 than I can get back on without blowing my savings every month. Can anyone help me with this, if so can I get super dumb instructions on how to fix this?, or am I stuck with paying an arm & a let just to keep in touch with the family? I am running Windows 8.1, my router is a TP-Link TL-WR841N Wireless N300.
