No Upgrade Page - Your Account = 404 error

Unfortunately there is no upgrade page in pro site. When you click "Your Account" or "You have x days" it takes you to the main site with a 404 error. Tried:

1. Turning off all plugins then activate pro site - same error.
2. Added all Paypal login and set-up info.
3. Disabled Free Trial and enabled it again.
4. Changed "Rebrand Pro Sites"

Nothing seems to work. Any suggestions?

Thanks, Dan
