Dear sirs I experienced a problem already reported on previous discussions, such as in: https://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg05069.html Following Bruce´s assumption that the antivirus must be the source of the crash of arthemis and athena, I disabled my free AVG antivirus and everything worked fine. With the antivirus on, it doesn´t work. Please, can anyone help me on how can I fix it? The log file is attached. Thank you for any help. http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail Virus-free. www.avg.com http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
