You can easily change the funding source (such as your credit card) in PayPal.
You may need to "Add" a new credit card or funding source. You can learn how to do that directly within your PayPal account (and it should be easy since you have already done it before).
To change your funding source for your Logical Forex Indicators…
Login To PayPal
Find the most recent Logical Forex Transaction in your "Recent Activity". This is usually on the default "first page" when you login to your PayPal account.
Click the "Details" link next to the Logical Forex Transaction.
Click the Subscription ID
The Subscription ID almost always begins with S- followed by a sequence of numbers and letters.
Although I have "covered up" most of the Subscription ID in this example, you can still see where to click. Just click that Subscription ID link.
Select Your New Funding Source
Select your funding source, and click the "Update Information" button.
For the new funding source to appear in your list of selections, you must have already created the "credit card" or other funding source using other links in PayPal. If you need to do this BE SURE TO NOT click the "cancel subscription" button! Just click the links at the top of the PayPal page to add a new funding source, then return to this page later.
