PayPal Error with Market Press

I got the following error when I tried to check out:

There was a problem connecting to PayPal to setup your purchase. Please try again.
10002 - Security error - Security header is not valid


    Excellent, glad you fixed it. :)

    Thanks for marking resolved as well.

    Was it incorrect API details against the sandbox or live API?

    Take care.
