Try reading all of the grompp output carefully - paying attention to 
warnings, etc. This error message can arise because you've mangled 
something elsewhere in the .top file and the parser gets lost. If all 
else fails, please post your full command line, the full output of 
grompp, your full .mdp file and your full .top file.
