AWS Keys ERROR HELP!!

Trying to plug in my AWS Keys to Woozone and I'm getting this error:

Amazon Error: 1 - SOAP Fault: (faultcode: aws:Client.AWS.InvalidAccount, faultstring: Your AccessKey Id is not registered for Product Advertising API. Please use the AccessKey Id obtained after registering at https://associates.amazon.ca/assoc_credentials/home.)

What am I not understanding/doing wrong?

Looks like the key you gave "is not registered for Product Advertising API". if it's supposed to be, are you providing the right key or have access to required ressources ?
