Sorry I saw that after...I posted!
You should already have that core in you F@H folder. That is the core for running Gromacs.
Have you had one of those before?
It should get tired of trying and move on itself, although I dont know how long it will continue to try.
I have never seen this! Looks like no one else here has either!
Some times restarting yor rig will help it to move on.
Its just a shot in the dark though!
Good luck and post back if it starts on this new animal!
I'll send it to you again from work..... at home the date was in Aug. sometime, and I ahven't seen that core on my home boxen for awhile......... but one of the ones at work was working on one yesterday morning, so I'll send you that one here in an hour or two when I get to work (damn snow)
