Hey guys, I'm only new to this whole theme thing, so please bare with me!

I've just installed the Ripple theme and it looks great on my site. Although when I go into the forum's to post a new topic and do not put a subject in and try to submit it, at the top of the page should be a box that says "You must specify a subject when posting a new topic." This box is there, but it looks as though the text colour is the same as the background!!
Is there a way to change it?
When I look into the source of the page generated, I see that it has:

Code:

<table class="forumline" width="100%" cellspacing="1" cellpadding="4" border="0"> <tr> <td><table width="100%" cellspacing="0" cellpadding="1" border="0"> <tr> <td></td> </tr> <tr> <td align="center"><span class="gen">You must specify a subject when posting a new topic.</span></td> </tr> <tr> <td></td> </tr> </table></td> </tr> </table>

I've tried changing /themes/Ripple/forums/forums.css and also /themes/Ripple/style/style.css but none of these seem to make a difference after refreshing the page..??
(The demo of this theme can be viewed @ http://www.olate.com/templates/demo.php?s=17 )

Any help would be great as this is the only annoying thing with this great theme!!
