Mandrill & WP Author Box Lite

Hi,

I installed the WP Author Box Lite plugin to my site and got this error:

Mandrill: wp_mail has been declared by another process or plugin, so you won’t be able to use Mandrill until the problem is solved.

Looks like somebody had the same problem few months ago, did you find a solution to this? I’m also using Mandrill to send WP transactional emails.
