[World was deleted after adding a plugin]

hey, did this ever get resolved? I've just had the exact same issue and I really want my world back. 

[My server reset for no reason at all after adding plugin.]

So I had a survival server with a few of my friends. I decided to add the plugin world edit to the server, and so restarted the server by pressing "stop" and "start". When I go on, it's a completely different world with none of the same items. Is there any way I can get my world back, or could an admin get the file somehow?
