My Salesforce Developer Edition (DE) org will be locked within the coming days, unless I can log-in to reactivate it. How can I log-in to reactivate it? What is the URL to do that? It's urgent, so any other relevant info will help. Thank you.

I looked through Q&A docs but couldn't seem to resolve the issue so far.
