Translation - Reply button text

I edited all of the available translation lines for Comments Plus. There's only one thing missing: the reply button, which keeps displaying "Reply".

Currently, Comments Plus is overriding my Wordpress, theme and comments.php language settings, no matter what I do. Is there an easy way to solve this and get the original reply_text value that I had input on my comments.php file?

I really love this plugin (even though google keeps reloading forever... I had to disable Google comments), but I'd need it fully translated.
