Hey, just thought I could throw some help in here.
If your IP is not in their ban-list, then there may be a few reasons why the site won't load for you.
1 - Your IP was banned. could be an accident, IE: failed to login too many times in a row
2 - You have a plugin/script running that blocks the site. I have AdBlockPlus for Google Chrome, and some sites won't load with it on. For instance, my site has all my images, css files, videos hosted on Amazon's S3.. And adblock blocks it by default. You can tell it to not block that site specifically, or remove the blocking for whatever it is (in my case, I removed the blocks for amazon's s3)
3 - DNS issue with your ISP
There are other reasons, but generally these are the top 3 reasons that I have troubles. Normalyl I don't get banned from places lol, but it is the most obvious. My ISP has issues with it's DNS. Sometimes, websites won't load for me. Like half the sites I try, won't load. It's weird. Then I manually change my IP address and boom, everything works great for a few weeks.
I recommend to first ensure you don't have any weird plugins, such as my adblockplus example. However, if your using the same browser when on the VPN, this probably is not the cause.
Try to change your IP address. I ONLY use Linksys routers, and almost every single Linksys router allows you to change the router's MAC address. You simply go to "MAC Address Clone" and change the mac to another valid mac, and save. Power cycle the modem and router, and you should have a new IP. You can first open ipchicken.com and keep it open. change your IP, then double check ipchicken.com to be positive your IP changed. It may be possible that your ISP still won't allow you to change your IP though. For most people, simply changing the MAC address of the first device on the network (usually your router) and rebooting everything will change your IP. I can do it 100 times a day if I wanted.
So yeah, try changing your IP address. It may make the world of difference.
You mentioned a VPS service. I just wanted to throw this out there... I use BlackVPN! They are like $7 for 3 months. You have to join using someone's referral code to get the extra 2 months, else it is only 1 month. Every person you refer to get a VPN, you get 2 weeks added. So 2 people a month, and you can continue to use the VPN for free! It is pay as you go, so if you don't pay they won't try to automatically bill you...
Yeah, a PREPAID VPN!!! Also, they DO NOT keep any logs what-so-ever! The logs are erased from memory before they are ever written to the hard drive! So a real anonymous VPN with no digital trail!
You can read more about them here in my thread:

Hope you get this resolved, good luck!
