Hi swu,
I think popups you have provided have nothing to do with a problem described in this post: it is about incorrect assemblies..
In your case, probably, the reason for exception/crash missing or incorrect settings files. Maybe you have selected portable installation, and installed files into folder from where HippoEDIT could not read them (because of the permissions). But it is strange, that this happened after HippoEDIT update, while I do not remember any fixes relevant to security done recently on my side...
BR, Alex
