Error 10002 means "authentication error".
This can be caused by several things, including but not limited to:
- wrong API signature details entered
- spaces left on the end of API details when pasting
- use of a sandbox signature key when trying to do live transactions
Also, have you applied the latest Express Checkout patch ?
