Hansaplastique on "[Plugin: WP-Filebase Download Manager] Update v 0.3.0.04 - "WP-Filebase not active" when editing posts"

After todays update, I get the “WP-Filebase not active.” message when trying to insert a short-code into a post.

WP-Filebase version: 0.3.0.04
Wordpress version: 3.8.1

Since I'm not in need of the new features, does anyone know how to get 2 versions back? (I noticed two updates in the past few days)
