Re-direction after signup submit button

Hi all, I purchased the full version of the plugin and tried to contact Josh for a bit of help on an issue I am experiencing with the plug in, but I assume he must be super busy because he hasn’t got back to me yet, so I am hoping someone else could.
Long story short.
When a user fills the signup form and hit the submit button the New User Approve plugin displays the message of pending approval and emails to the interested parties are generated, as it should. At that point the signup form should disappear and re-direct the user to a pre-profile page, where he/she can to some basic stuff before being fully approved.
Unfortunately the re-direction doesn’t happen, leaving the user with the sign-up form still displaying all the details just filled in.
I need to find a way to fix this.

I noticed that there is a section of the new-user-approval.php that is meant to force a redirection stated on the main theme, and I found the bit of code on the theme that is supposed to handle that, but I cannot go further than that. I was wandering if it was possible to force the plug-in to set a specific page to redirect the user after the registration process, instead of honoring the theme…
I tried ” header(“Location: … ” but got an error message saying that header is already in use by a SEO plugin, which I tried than to disable, and again got an error saying that header was in use by the theme itself…

Any help would be highly appreciated.
