question: more tag & Blix theme

Hello everybody.
I am building a site with WP, using Blix theme. This problem came around and I can not find the solution (even after searching here):

I am using ‘more’ tags instead of using excerpts, find it more easy to configure the text that way. Page is not in English, and at the end of post teaser message it shows (more…), which leads to full article. How do I translate this hardcored stuff into my language?

Not very well versed in php, but I suspect that this piece of code does it:

'<?php ($post->post_excerpt != "")? the_excerpt() : the_content(); ?>
<p class="info"><?php if ($post->post_excerpt != "") { ?>" class="more">Continue Reading<?php } ?>'

– which means (to my understanding) that IF there is an excerpt (which I do not use), then we have ‘Continue Reading”, which I can translate, otherwise it shows the same “more”. How to translate/change this?
