Default Sky replacement files disappeared?
Hi,
This afternoon I was fiddling with the new sky replacement features, using the default skies. For whatever reason, I got a crash and now every time I come to use the feature I get "Could not complete your request because the file could not be found" every time I select a default sky. I've identified the folder I believe the files should be in, but they're not there. Is there any way that I can reinstall the files? I've already done a reinstall but kept my preferences - will I need to do a completely fresh install to get them back?
I'm able to add my own files and it works fine, but i'd like the default ones back!

Is the error I get. Thanks!
