One website page looks wrong in IE9 after template propogation

Question

For some years I have been updating about 10-12 pages in my website each month from a template (in Dreamweaver CS3).  The change is just a date update.  After the September update, one page of the relevant child pages is displaying the date in the wrong font and colour.  I have tried re-putting but the error is stuck.  Trying different fonts and colours just results in other wrong fonts/colours.  This one page is out of step.
I do not know why this is happening.  Particularly as Chrome and Firefox display all pages correctly.
The offending page is here:

When viewed in IE9 the date is rendered differently to the other main pages linked in the lefthand side table.
Grateful for any explanation or remedy.
Thanks.

Answer 1

You have 2 embedded CSS styles effecting this date
<p class="style57"><span class="style66">SEPTEMBER 2011</span><br>
</p>
In your embedded CSS, you have multiple rules for .style57 and .style 66.  Suggest you comb through the code carefully & resolve conflicts.  Also as Murray said earlier, remove the HTML comments <!--  --> from your CSS code.
.style57 {
    color: #66FF99;
    font-size: 10px;
    font: tahoma;  /**remove this**/
    font-weight: bold;
    font-style: normal;
.style50 {color: #CC9900}
.style51 {color: #FFCC00}
.style52 {
    color: #66CC66;
    font-weight: bold;
.style53 {color: #66FFFF}
.style55 {color: #FFFF66}
.style56 {color: #FFFFFF}
.style62 {color: #336699}
.style63 {font-family: Tahoma}
.style64 {font-size: 18px}
/**is this the style you want?**/
.style66 {color: #99CCFF}
.style68 {font-size: 14px}
.style72 {color: #33CCFF}
.style73 {color: #7FDF55}
.style74 {color: #2AFF55}
.style75 {color: #FF7F00}
/**duplicate style**/
.style57 {
    color: #66FF99;
    font-size: 12px;
    font-weight: bold;
    font-style: normal;
    font-family: Arial, Helvetica, sans-serif;
.style64 {
    font-size: 14px;
    color: #FF9999;
/**another duplicate style, REMOVE THIS **/
.style66 {
    font-size: small;
    color: #FFFFFF;
