I found out that, in order to get Cover Art for the CDs that I want to rip using XLD, I need to provide Access Key and Secret Key from AWS (Amazon Web Service). So I did create an AWS account, and downloaded the Excel file that has the Access Key and Secret Key, and put the Key in the blanks in Preferences. However when I click on "No Image" where the cover art should be, it says "Parse error: The operation co..."
When I searched the problem, I found this:
A comment from 2016 says: "Recently AWS changed their policy and they don't accept query which only have access key and secret key. In addition to two keys now Amazon associate ID (associated with the keys) is mandatory, and current version of XLD doesn't have an interface to enter the ID. So simply the feature doesn't work for all users at the moment."

I will followup my last post with a solution.

Like in the first comment was written by @tmkk - the AWS policy and guidelines changed, and now changed again to AWS API Verison 5.0. I use the api also in other tools and after a long trial & error all works fine now.
So please read the AWS docs and follow the instructions, how to transfer you current API account:
https://docs.aws.amazon.com/AWSECommerceService/latest/DG/becomingDev.htmlAfter that create a new API key (max 2 allowed for free) and the read carefully the "Efficiency Guidelines" because Amazon limited the free access to the API (for eample request-limits or performance within the last 30days etc.):
https://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html#efficiency-guidelinesWhen you observe all points in the guidelines the API works fine after some days and XLD find covers like before.

Hope that helps,
Sven
