Please check carefully what happened during the minimzation. The energy at
step zero of a subsequent MD should match the energy at the end of the
minimization. Since you have very wrong energies at step 0 (see the "***"
entries), then either something went wrong on the minimization, or somehow the
MD is not starting from the ending structre of the minimization. [Or, maybe
some other problem, but those are the most likely explanation.]
