Hello, I wonder if anyone can help me. Artemis (version 0.9.25) is unable to open the most recent project files that I have created and just crashes. These files also can't be opened on a different computer. I get the following message in the dartemis log file: You must define a method name at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\vendor\lib\Class\MOP\Mixin\HasMethods.pm line 96 Class::MOP::Mixin::HasMethods::has_method('Class::MOP::Class::Immutable::Moose::Meta::Class::__ANON__::SERIAL::1=HASH(0xb49ab58)', '') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\Atoms.pm line 424 Demeter::Atoms::parse_line('Demeter::Atoms=HASH(0x10140bd0)', ' :') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\Atoms.pm line 447 Demeter::Atoms::parse_line('Demeter::Atoms=HASH(0x10140bd0)', 'space = I 41/a m d :2') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\Atoms.pm line 382 Demeter::Atoms::read_inp('Demeter::Atoms=HASH(0x10140bd0)') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\Atoms.pm line 198 Demeter::Atoms::__ANON__('Demeter::Atoms=HASH(0x10140bd0)', 'C:\Users\mhammer1\AppData\Roaming\demeter\stash\_dem_aaczdzkl\feff\qynwh\atoms.inp', 'C:\Users\mhammer1\AppData\Roaming\demeter\stash\_dem_aaczdzkl\feff\racrw\atoms.inp') called at accessor Demeter::Atoms::file (defined at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\Atoms.pm line 202) line 10 Demeter::Atoms::file('Demeter::Atoms=HASH(0x10140bd0)', 'C:\Users\mhammer1\AppData\Roaming\demeter\stash\_dem_aaczdzkl\feff\qynwh\atoms.inp') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\UI\Atoms\Xtal.pm line 667 Demeter::UI::Atoms::Xtal::open_file('Demeter::UI::Atoms::Xtal=HASH(0x1afa1b38)', 'C:\Users\mhammer1\AppData\Roaming\demeter\stash\_dem_aaczdzkl\feff\qynwh\atoms.inp') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\UI\Artemis.pm line 1388 Demeter::UI::Artemis::make_feff_frame('Wx::Frame=HASH(0x1522a180)', 'C:\Users\mhammer1\AppData\Roaming\demeter\stash\_dem_aaczdzkl\feff\qynwh\atoms.inp', 'CuCr2O4_I41-amd2_2006190') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\UI\Artemis\Project.pm line 351 Demeter::UI::Artemis::Project::read_project('HASH(0xf7cdf60)') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\UI\Artemis.pm line 996 Demeter::UI::Artemis::OnMenuClick('Wx::Frame=HASH(0x1522a180)', 'Wx::CommandEvent=SCALAR(0x15dc4558)') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\lib\Demeter\UI\Artemis.pm line 440 Demeter::UI::Artemis::__ANON__('Wx::Frame=HASH(0x1522a180)', 'Wx::CommandEvent=SCALAR(0x15dc4558)') called at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\bin\dartemis.bat line 50 eval {...} at C:\Users\mhammer1\AppData\Roaming\DemeterPerl\perl\site\bin\dartemis.bat line 50 So I guess I need to define a method name? What could it be and how do I define it? Thank you for your help (in advance!)
