Hi, If the topology works e.g. for drug in water, and you get problems with blowing up only with the complex, then likely the starting pose is crude, e.g. gaps with missing solvent, or overlapping atoms. Use a visualization program and look carefully. The standard advice here applies: http://www.gromacs.org/Documentation/Terminology/Blowing_Up
