As I attempt to try again with with only 30 files, HEN is now starting with the text "Update Server Responded with an Error" or something like that.
It looks like it loads HEN, but when I launch IRISHman, it freezes after I select "File Manager".
You could try to go offline so that HEN doesn't try to update itself.
However if IrisMAN starts I think HEN is running. I don't know why it freezes but I notice some weird behaviour with IrisMAN: when I have a specific 3rd-party wireless gamepad adapter plugged into USB, then I cannot properly enter a few IrisMAN sections like the File Manager :/
