WARNING: screen [GScreen0] not found

maybe the problem is cause you using java 1.6 in dev?

I've tried to load your file, are you sure that you have the images in the dropbox folder? I don't think it's a java version problem. Nifty-editor has 1.6 for target jvm version.

yes the settings are all correct

i found a workaround
start editor > click WorkGUI > delete GScreen0 > load XML file
with this i have no trouble to load the file
