ERROR Code CMN.ATO.PAYEVNT.EMM99507

I recently moved from Myob accountright to Myob business. I have followed the instruction on how to set up stp phase 2 in myob business. I have edited it and resubmitted it making sure that the old id and new id are both correct. 15 times. Unfortunately I continue to get the rejected message with the same error code as listed above. I spoke with the ato yesterday and they confirmed that they could see both of the id on the access manager. I am wondering if I should be saying no to the question as both are myob products. Could this be the issue? I finalised all of the employees and transfer as the reason for termination as we sold the business and all employees were give a job with the new owners. It is showing tax ready in the employees ato account. I only have 2 employess left with the company now hence the change to myob business.
