Adobe Express Webpage completely lost my work; no version history

Hi Adobe Express Team,

I was working for ages on my adobe express portfolio webpage to create a portfolio for my friend.

This involved uploading photos and many pages of text. Then when I went to publish the link it the "share" button was completely greyed out and it had deleted all of my pages. 

I can't see any way to look at version history so now i've lost 2 hours of my time and also missed an important deadline. Please help.

I was using;

1. Adobe Express Web Desktop

2. Windows 8 

Thanks,

April
