Responses aren't showing in plugin

Hi there, I have already sent you an email at "Contact Us" tab since Saturday but i haven't take an answer yet! I hope my chances are better this time. Anyway, the issue i'm facing with Easy Discuss, is that when i enabled the "Content-EasyDiscuss" plugin so that someone can respond at some articles directly, even though you can write normally your response, once posted, you can't see what is written, no matter if you are guest, registered member, super user! Under the article all i can see is 'Responses(1)' and when i press the 'View Discussion' button on the right, instead of the discussion, it says:

<<There are replies in this post but you are not allowed to view the replies from this post>>.

Only from the backend panel i can see what these responses write! I really think that the solution is simple but i haven't figure it yet. Any help is appreciated...
