Configurator again not working

[Cylob]

Did you try another browser?

Yes, I tried that, also on mobile (loading the online version), even on 4G to circumvent any LAN blocks. It is not that. A new online generated config file works fine on all browsers so I would not suspect some form of permission issue. The configurator makes a distinction between old (more than about 5 weeks) and new config files, also the ones stored online that could be opened and edited 6 weeks ago. Maybe it looks at the date.

Can you edit any previously made config files, Cylob?

I did try and open some old config files both locally stored and saved configurations in my devialet profile online and made changes to them. I even saved one locally and reloaded them into the configurator. (Didn't try and load them on my D200 though). So it seems to work for me.
Using Chrome btw.
