File is missing on Creative Cloud website but available on XD home screen (except I can't open it)

I was working Friday on a couple of files in the cloud. Comes Monday, I can see my file(s) on the XD home screen, but when I try to open or download them, it doesn't work. And if I go to assets.adobe.com/cloud-documents the files don't show up, I can see the folder I saved them on but when I open it, it's empty. It also happens to any new document I try saving on the cloud and opening later on (error 47).

Yes, my XD and CC are updated. Yes, I tried uninstalling and installing them both again. Yes, my internet connection is fine. I did try to duplicate/rename the files on the CC Desktop, tried opening/downloading them on the CC Desktop, none of those worked. The one thing I couldn't try was opening them on a different machine, cause I only have the one. I spend the entire day yesterday (Monday) trying to fix it.

Any idea what I could possibly do to get those files to open so I can save them locally?
