You haven't addressed any of the comments or questions I posted earlier:


When asking for free help, demonstrate that you're willing to take the advice 
you're given, and if that fails, state what problems remain.  Otherwise, it 
seems like you're ignoring viable suggestions.

For the sake of being explicit: your .mdp file is wrong, and the dynamics are 
likely spurious.  Solve these issues (which I have described for you!) before 
moving to a more peripherally-related solution.  Also check the .log file; as I 
said before, Gromacs rarely exits without offering its own error messages about 
what's going wrong.  There is nothing in this output that immediately suggests 
your PME spacing is remotely at fault, but other parameters in your .mdp file 
are clearly wrong.
