I'm trying to follow the instructions located here: http://beta.appinventor.mit.edu/learn/reference/other/tinywebdb.html

When I go to deploy the webDB app, after creating a new Project (the instructions say create an Application,  but all I can see is Create a new Project, so I'm hoping that's the same thing), I get the following messages: 
 
Starting update of app: npicswebdb, version: 1
12:49 PM Getting current resource limits.
2016-03-09 12:49:16,329 ERROR appcfg.py:2396 An error occurred processing file '': HTTP Error 403: Forbidden Unexpected HTTP status 403. Aborting. 
Error 403: --- begin server output ---
You do not have permission to modify this app (app_id=u's~npicswebdb').
--- end server output ---
2016-03-09 12:49:16 (Process exited with code 1)

I am logged in to App Engine online. I haven't found anywhere in the App Engine Launcher on my desktop to login or somehow specify that I am authorized to access that app engine project from my desktop. There's no indication of having to do that in the instructions. Any ideas?

Hello Paul,

I've tested the sample application provided at the link above and despite throwing a warning for deprecated Python 2.5 runtime, it deploys successfully. So the issue you're facing is indeed with project permission.

At first make sure the user account you're deploying with has either 'Owner' or 'Editor' permission for the project by visiting the permissions page. If you need to add a user account, make sure to accept the invitation by logging into the invited account.

You can then open App Engine Launcher and select 'Control' -> 'Clear Deployment Credential' to delete any saved credentials. The next deployment attempt should prompt you for granting access to the launcher. Before you hit 'Allow', make sure you're logged in with the correct user account (top right corner).

I hope that helps. Cheers!

I have no idea how that fixed it (I already had the right permissions), but for whatever reason that has indeed fixed it. Thank you soooooo much!!!
