CB 2.0 broke roundcube?

Hi,
Been going through the threads and can't really find anything about it, but I recently (ok, so I am late) updated to CB 2.0 and when I did, it seems roundcube is no longer working since it got upgraded to 1.3.4 my users are seeing:

CONFIGURATION ERROR
config.inc.php was not found.
Please read the INSTALL instructions!

on the login screen - but I can't find anything in my forum search to point me to a fix.

Anyone?
