PayPal Express Checkout Error

I am getting the following error when trying to use Express Checkout:

PayPal gateway has rejected request. Security header is not valid (#10002: Security error).

I\’ve triple-checked my credentials from PayPal and they are correct. The error codes on the PayPal website don\’t offer any assistance on how to correct this issue. Has anyone else had any trouble with this?

I am using Magento 1.4.1.1. In my test environment, the sandbox account worked perfectly…
