MT4.2 pro - problems with Category-Monthly templates

Hello Guys...

I'm recently upgrade my MT4.1 to 4.2Pro to give a try in the comunity functionalities. Unfortunally, when trying the rebuild of the templates, I had an error when rebuilding the Category-Monthly templates... It keep complaining with this error:

Publishing file /home/bjunior/blog.uncovering.org-mt4/archives/artes-e-letras/2003/12/index.html... Use of uninitialized value in join or string at (eval 155) line 2. Error rebuilding file /home/bjunior/blog.uncovering.org-mt4/archives/artes-e-letras/2003/12/index.html: Parameter 'Entry' is required job failed: Error rebuilding file /home/bjunior/blog.uncovering.org-mt4/archives/artes-e-letras/2003/12/index.html: Parameter 'Entry' is required

The template is nothing special... something like:

    <a href="<$MTEntryPermalink valid_html=">" title="Clique para ler este artigo" class="thumb_image">/_150x113.jpg" title="Clique para ler este artigo" border="0"></a>   

    <a href="<$MTEntryPermalink valid_html=">" title="Clique para ler este artigo" class="thumb_title"></a><br />
    <p>...
        </p>
