Securitiy header is not valid

Hi, i want to use your plugin for paypal express checkout.
When I press the Express button in the shopping cart, I get the following error message:

An error occurred, We were unable to process your order, Please try again.

in the log files i can see the following error:

I know that this error can have something to do with wrong access data for paypal. I use for:

Live API Username = PayPal account
Live API Password = Client ID
Live API Signature = Secret

i hope this is correct?

best regards

Tom
