[General] World editor crashes when opening map

[givecake]

Hi all. I've been building a map in Shanghai. I came back to UK, and sent the map to my email. When I got back, I tried to open it, but it crashes the world editor. I sent it to a friend and he can open it just fine.

I am flummoxed. Currently reinstalling, but wondering if anyone has any ideas as to why this is happening?
The computer I was using in Shanghai had a Chinese Windows 7 on it, and my friend who tried it just now has a Finnish language Windows 7 on it. My computer has an English Windows 7 on it. I'll update here if there is any change with a reinstall.

Ok. A reinstall fixed it. It is odd though because other maps were loading fine..
