Trouble with <p> tags – There is no line break

All the pages are having trouble, but this is the one that I am currently working on: KRA Entertainment ? The Christmas Story.

I am not sure what the problem is, but my <p> tags are not adding a blank line after the </p> tag. Here’s the HTML Source:

<table width="100%" cellpadding="4" cellspacing="0" border="0" align="center" class="contentpane">
<tr>
<td width="60%" valign="top" class="contentbody" colspan="2">
<p>Paragraph number one goes here with a lot of information about the video on this page, and I think my problem is in the style sheet, but I’m not sure. I should have a blank line right after this paragraph.</p>
<p>This is the beginning of paragraph number 2. As you can see, there’s no line break between paragraph number one, and paragraph number two. The next line break should be here.</p>
<p>Paragraph number 3 begins here, and end here.</p>
</td>
</tr>
</table>

I’m sure that there’s something wrong with the theme that I’m using(3×3 beta), because if I switch to the default theme, the <p> tags work fine and I get the line break that’s supposed to be there.
