Hi,
I’m sorry your first experience has been frustrating.
I’ve fixed the links you mentioned on the setup page.
As far as the keyfile issue you were seeing, that is usually indicative of AWS user permissions. I’m glad you were able to resolve it with a new stack, however.
As far as the Ion deploy issue, we would need to look at the specific errors in your Datomic system logs to determine the issue with the deploy. You can find details on how to search your logs here: Where to look in AWS when deploy (not push) fails? and https://docs.datomic.com/cloud/operation/monitoring.html#searching-cloudwatch-logs
