"Articles" plugin not working after update

Hi All,

I recently updated my site to 2.2 from 2.0.7 and installed the Articles plugin. It wasn't showing up, so I cleared all caches and flushed all sessions, and then the "Create new article" option began appearing in the context menus. I clicked it and successfully created a news area, but now when I go to edit the news container, I get a blank screen. If I go to create a new article, it correctly shows. Weird.

I've tried clearing cache/flushing perms ago, to no avail. Any ideas here would be mucho appreciated!
