I was able to access Project Web App (PWA) and navigate without any problems.
When I attempted to download Microsoft Project (the client), I get the following message: "Your admin has turned off Project installs. Contact your admin for more information about how to get Project in your organization."
I checked the settings within Office 365 Admin panel and the option WAS set to allow download.
This problem was duplicated by two different people on two different machines.
Please help.
Thanks!
I didn't find the right solution from the Internet.
