HOWTO: Cancelling your ISXEVE Subscription
Since ISXEVE handles subscriptions through paypal.com, cancelling your subscription is VERY easy. First, go to www.paypal.com and log in using your account information. Once you're viewing your account history, search for the initial subscription creation that you did for ISXEVE (you might have to use the search option.) Although these screenshots were taken in reference to an ISXVG subscription, it should look something like this:
Click on "Details" and then click on "Cancel Subscription" in the screen that follows (showing here):
Then, another confirmation window should pop up that looks like the screenshot below. Once there, click on "Cancel Subscription" again, and you should be finished!
Once your subscription is "Cancelled", your ISXEVE authentication will continue to work until the end of your monthly payment cycle.
