2 Things to mention.
1St: When you click on the Shareware “Download” link, if you have an ad-block program running, it will mess things up so pause it. If you do not, the code you use to redeem for the service, is mentioned on that page, and also on the email page that Shareware sends you. It may be down a bit on the page but it is there.
2nd: Unlike some other VPN services, VPN Unlimited will not allow elongating your subscription an additional 6 mths with any of these codes. It’s unfortunate, but it is their decision not Shareware’s.
“If you do not,” should have stated “If you do not have an ad-block program running,”
