Hi Roberto, Since uninstalling and installing didn’t helped, you could give a try by doing a System Restore to the restore point when it was working. Try to Run as administrator if you haven't tried. cheers Atul From: Rodriguez, Roberto Sent: Wednesday, May 29, 2013 7:57 PM To: ifeffit@millenia.cars.aps.anl.gov Subject: [Ifeffit] Bug Report - (D)Athena Doesn't Open I’m currently having trouble opening both (D)Athena and (D)Artemis. When I first installed Demeter a couple months ago, the programs worked properly without any issue until recently. In both cases, the command prompt and the splash screen appear momentarily, disappears, and then nothing happens - the program never opens. To my knowledge, no settings have been changed that would prevent Athena/Artemis from opening. In contrast, (D)Hephaestus and (D)Atoms open and appear to function properly. I’ve tried uninstalling/reinstalling Demeter 0.9.13.1 in addition to installing the Updater 0.9.17, but I keep having the same issue. Any suggestions would be most helpful. Operating system is Windows 7 Enterprise.
