Header alignment using .div CSS

[ChU v2]

I'm having trouble aligning the header template the way I want. I used a .div defined in Main CSS to locate my "login box" image. but when I try to right align next to my logo it goes all crazy.

Here is my header code.

<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>
    <td align="center"><img src="$stylevar[imgdir_misc]/xbox_header.png" border="0"></td>

<td align="right">
<div class="div13" align="center">
<br><br>
<if condition="$show['member']">
        
            <strong><phrase 1="$bbuserinfo[username]">$vbphrase[welcome_x]</phrase></strong><br />
            <phrase 1="$pmbox[lastvisitdate]" 2="$pmbox[lastvisittime]">$vbphrase[last_visited_x_at_y]</phrase><br />
            <if condition="$show['pmstats']"><phrase 1="$vbphrase[unread_x_nav_compiled]" 2="$vbphrase[total_x_nav_compiled]" 3="$session[sessionurl_q]">$vbphrase[private_messages_nav]</phrase></if><br />
            <if condition="$show['pmwarning']"><strong><phrase 1="$vbphrase[pmpercent_nav_compiled]">$vbphrase[your_pm_box_is_x_full]</phrase></strong></if>
        
<if condition="$show['member']">
            <a href="http://www.xboxinformer.net/forum/login.php?do=logout&amp;logouthash=0aa8481865a81b9273381ebc87d7966c" onclick="return log_out('Are you sure you want to log out?')">Log Out</a></td>
</if>
</div>
</div>
    <else />

        <!-- login form -->
        <form action="login.php?do=login" method="post" onsubmit="md5hash(vb_login_password, vb_login_md5password, vb_login_md5password_utf, $show[nopasswordempty])">
        <script type="text/javascript" src="clientscript/vbulletin_md5.js?v=$vboptions[simpleversion]"></script>
        <table cellpadding="0" cellspacing="$stylevar[formspacer]" border="0">
        <tr>
            <td class="smallfont"><label for="navbar_username">$vbphrase[username]</label></td>
            <td><input type="text" class="bginput" style="font-size: 11px" name="vb_login_username" id="navbar_username" size="10" accesskey="u" tabindex="101" value="$vbphrase[username]" onfocus="if (this.value == '$vbphrase[username]') this.value = '';" /></td>
            <td class="smallfont" colspan="2" nowrap="nowrap"><label for="cb_cookieuser_navbar"><input type="checkbox" name="cookieuser" value="1" tabindex="103" id="cb_cookieuser_navbar" accesskey="c" />$vbphrase[remember_me]</label></td>
        </tr>
        <tr>
            <td class="smallfont"><label for="navbar_password">$vbphrase[password]</label></td>
            <td><input type="password" class="bginput" style="font-size: 11px" name="vb_login_password" id="navbar_password" size="10" tabindex="102" /></td>
            <td><input type="submit" class="button" value="$vbphrase[log_in]" tabindex="104" title="$vbphrase[enter_username_to_login_or_register]" accesskey="s" /></td>
        </tr>
        </table>
        <input type="hidden" name="s" value="$session[sessionhash]" />
        <input type="hidden" name="do" value="login" />        
        <input type="hidden" name="vb_login_md5password" />
        <input type="hidden" name="vb_login_md5password_utf" />
        </form>
<a href="http://xboxinformer.net/forum/register.php">Click Here to Register!</a>
</if>
        <!-- / login form -->
    
        </td>
        
        </div>

</tr>
    </td>
</tr>
</table>
<!-- /logo -->

<!-- content table -->
$spacer_open

$_phpinclude_output

.div13

.div13 {
background-image:url(http://www.xboxinformer.net/forum/images/xbox/misc/loginbox.png);
background-repeat:none;
border:0px solid; border-color:black;
width:300px; height:124px; overflow:none;}

Thanks for any help
