Hi Matt, Shoaib (and Bruce lurking in the luminiferous ether),

I have 8.1 x64 on my laptop and just upgraded to 0.9.19 - clean install.
I can offer some additional details on this problem.

I read in a file in DAthena, extracted the chi(k) and saved the project.
All buttons worked. When the file was read in, 4 mini-graphs displayed,
and I could select k, E, R as desired for full graph.

The second time I run it, reading in the exact same file, only the energy mini-graph
displays and the E,k and R buttons no longer produce any graphs.

From the clean install, I saved the DAthena.prj. I started DArtemis, read in the DAthena.prj
file, haven't tried fitting but saved the DArtemis fpj file.
If I try re-opening the fpj file I just saved in DArtemis, DArtemis crashes,
but re-opening the DAthena prj file after starting DArtemis is not a problem.

In DAthena, if I go to the appdata/roaming/demeter directory and delete the demeter.ini file, DAthena will display all 4 mini-graphs when I open the prj file and the k,R,E buttons work.

I uninstalled and went back to DAthena seems to work - all 4 mini-graphs, and E,k,R work. DArtemis still opens, reads DAthena.prj but crashes when trying to read fpj file created under

Going back to the last 0.8.0nn versions, no crashes from Artemis or Athena.

Hope this helps.

I have recently upgraded my computer to Windows 8.1 Pro x64 and after this
upgrade I can’t run Athena and Artemis. The problem symptoms are:

1-      If I use Demeter version 0.9.13, Athena opens but when I try to open
previously saved file, Athena simply crashes without showing any error.
Artemis also shows similar behavior.

2-      By using latest build Demeter 0.9.19, Athena behavior is slightly
different it opens the files and show the plot. But pressing the E,k,R
buttons does not change the plot. Artemis still crashes by opening any
project file without any error.

I have tried following things, installed in compatibility mode of Windows7.
Athena worked fine only once after installing in compatibility mode.

Installed in different drives but situations remains the same. Tried to “run
as Admin” but no improvement.

Installed Demeter on three different computers running Windows 8.1 x64 but
similar behavior is received.

Kindly suggest me some work around because I have to use Demeter on almost
daily basis. I have attached log file obtained from Demeter 0.9.13 running
under Window 8.1 x64.

I think you might be in mostly uncharted waters with 64-bit Windows 8.
  I have access to many Windows machines, but I don't know of any
64-bit Windows 8.1 machines in our group.

If you're up for it, it might be worth installing demeter from source
from the github repository, following
and asking for help if you get stuck.

I'm sure it would be a great help to others if you did this....
