Hello fred99999au,
I'm sorry you're experiencing login difficulties. It sounds like there might be an issue with your Microsoft account. I recommend reaching out to Microsoft Support for further assistance, they should be able to help you resolve the problem.
Additionally, as I mentioned earlier, Microsoft Partner Center falls outside the scope of Advertising. For any related concerns, Microsoft Support will be the best point of contact. I appreciate your understanding, and I hope you're able to get everything sorted soon!
