Scene created on Mac doesn't open on Windows

So I reported this a while ago and it worked again so I closed the bug but now it’s back. I have created a level that, when I boot into Windows to load for Oculus Support, just gets stuck at the Loading… splash screen for UE indefinitely. It’s a huge problem since I need to present something for Oculus Rift soon and the Mac version has no support for it so I’m kind of screwed here. Can someone post an FTP or something where I can upload the files? It’s too big for Dropbox.
