Ah, unlike in Axure RP 7.0, the "Pro" edition in 8.0 isn't the same edition that gives you team projects. In 8.0, the "Team" edition is the one that gives you access to team projects, so 8.0 Team is the equivalent of 7.0 Pro, whereas 8.0 Pro is the equivalent of 7.0 Standard. Did you have a Standard license in 7.0 before you upgraded to 8.0? If you just bought the license and meant to purchase "Team" for the team projects, you can upgrade your license from Pro to Team through the customer portal. If you run into trouble with logging in to the portal, feel free to email us at firstname.lastname@example.org so that someone can take a look. Thanks!
