Thank you for reaching out. Hopefully, this issue has been resolved, but to answer your question, our Support Team has not had reports of clients unable to load their profiles. I recommend submitting a Support ticket if this continues to occur. Additionally, we have a Status website that can provide you more insight on sitewide issues:
Please let me know if this helps.
Glad to help. When submitting a request for a demo, someone should have reached out to you via email to provide you with account info, however, since it has been about 3 months since you posted this issue your demo account may have expired. I am unable to access your demo account and it's not recommended to post any account information within this forum, so I would suggest resubmitting a demo request here: https://tealium.com/cdh-demo-2/
There is a comments section where you can explain that your demo account didn't work and even reference the URL of this forum post. Our team will happily set you up with another demo account.
