C.K. Lee,
   I would recommend that you open the *.lst file using a text editor; 
sometimes error messages such as this are written just after the 
offending equation is written so you get an idea of which equation 
caused the problem. If that does not help then I would recommend that 
you send the *.tpf and *.lst files to your distributor for assistance.
Kind regards,
  David
