The License Keys are tied to your Salesforce Org Id and these change from Production to Sandbox.
You need to locate your Salesforce Org Id and then send a request for the License Key to support @ payments2us.com
Can I use my Production License Key in Sandbox?
Why do I get an error with Program/Area: BPAYUtil.docreateCRNsPost, Organisation (00Dxxx) does not have BPAY CRN License.
Can I use my Production License Key in Sandbox?
Why do I get an Error "License key is not valid. Please make sure the exact license options, license expiry date and key are entered as provided by AAkonsult. Do not try to select license options that are not included."
