add a Button

I am having a small issue with customizing the UserProfilesMadeEasy plugin. https://codecanyon.net/item/user-profiles-made-easy-wordpress-plugin/4109874

Here is what I am trying to do…..
On the‘Tutor Registration’ page
(starTUTORs.com click ‘Tutor Registration’ on top menu)
there is a submit button that is currently taking visitors to a page that will allow them to select the paid option they wish.

What I would also like to do is have another button next to that submit button that would take them to a Free Trial page.
I have tried to manipulate the code to add another button, but the plugin seems to be stopping me… or… is it my theme… or… maybe it’s something else …. Who knows ?
Do you ?

Only thing I know is the it’s not this

classes/class-upme.php file and method name is show_register_form

My tech guy said so and… so did plugin support who asked to have a look for me but… who now seem to have vanished.

FYI,
site has s2member and the InFocus_BuddyPress_Child_Theme
does this matter ?
