Hey. Nice work on this!

But I have one little problem with key configuring in the GUI. When I try to open the key configurator, it says "Couldn't open previous key config", and gives "done" button. When I press it, the configurator opens, but all keys are just pointing "0". You can change them as you want, but when trying to save the configuration, it says "Something goes wrong, check permission to keys file"

Root permission has no effect with it.
