Dear Monica Viglianco,
Thank you for reaching out to Microsoft support. I'm sorry to hear that you're experiencing issues with Microsoft Project.
To answer your first question, as far as I know, you do not need to use Office 365 to use Microsoft Project. You can purchase and use Project as a standalone product.
Regarding the issue you're experiencing with the free trial, it's possible that there may be a delay in setting up your account. However, waiting for 3 hours is quite unusual. I'm afraid this issue is related to the backend where it needs to further check by the related team who has higher permission to check issue from backend.
Therefore, I recommend contacting Microsoft support directly for further assistance. They will be able to investigate the issue and provide you with a solution.
You can contact Microsoft Phone Support. Reference: Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn
From there, you can chat with a support agent or request a call back.
Let me know if you have any further questions.
Appreciate your patience and understanding and thank you for your time and cooperation!
Sincerely,
Tina | Microsoft Community Moderator
