Updating or Installing Stack Ideas Products - 404 Category Not Found Error

Hey guys,

I am trying to update EasySocial but keep returning a 404 Category Not Found error. As a result of this error, here is the testing process I went through in order determine if the issue is on our end or in relation to the installation package.

1. Attempted to install EasySocial through Joomla Install Manager - FAILED with 404 Category Not Found error (see attached image)
2. Attempted to install Komento - Full Package - FAILED with 404 Category Not Found error
3. Attempted to install EasyArticles - Full Package - FAILED with 404 Category Not Found error
4. Attempted to install other Component packages for comparison: (see attached images)
- Akeeba Back-Up --> SUCCESSFUL install
- JCE Editor --> SUCCESSFUL install

Not sure what is up - hoping you guys have a quick and easy fix for this
