[texhax] need help for solving a problem in Tex

[P.L.K.Priyadarsini]

   Dear Sir/madam,

        I have to send a paper for conference. They ( conference  
organisers ) have sent a class file along with a template. They used
    \begin{abstract}
    \end{abstract}
    \section{introduction}

  etc in their template. I am getting the following errors when I  
compile my tex file as well as the template sent by them.
----------------------------------------------------------------------------
   1.  paragraph ended before \@startsection was complete.
        \par
        1.55   \begin{abstract}

   2. missing number treated as zero
        <to be read again>
                  }

        1.55   \begin{abstract}
   3.  Illegal unit of measure ( pt inserted )

          <to be read again>
                  }

        1.55   \begin{abstract}

   4.  Extra } or forgotten \endgroup
-----------------------------------------------------------------------------


  I am not getting these errors if I don't use the class file and  
simply i give document class article.


  Please help me to come out this problem
