My Windows 8.1 PC and Windows Phone 8 apps that interact with SkyDrive cannot upload or download files.  When I try this I get a few different error messages but I'm sure they're all related.  I recently changed my Microsoft Account password, but this is the only glitch I've encountered.   I also changed my display name from Eric F to Eric J F, but I can't imagine that had any effect.

The apps that are a problem are listed in my MS account settings under Account Settings/Permissions/Apps and Services.  The various app error messages are:

Problem uploading to SkyDrive:  An error occurred while retrieving the resource.  Try again later.

Unable to retrieve folder properties on SkyDrive.

Cannot connect to SkyDrive.

I've tried the following with no success:

Logging in and out and restarting

Uninstalling and reinstalling the apps

Removing the permissions (from above) and reinstalling the apps

Creating new files and/or folders for the apps

Re-syncing the app licenses

Copying. pasting, moving, and deleting to and from SkyDrive works fine, so it's an app-related issue.

Any insights or suggestions are appreciated!
