I've been using Ancestry.com for over a year now and got back to the early fifteen hundreds (I'm from a long line of peasants btw

). Yesterday I logged into my account and looked through a few records before going back to the pedigree page. I clicked on my grandmother and '****' my entire family tree disappeared. I messed around trying to get it back but when I had no success, I called admin. Admin said they unfortunately can't do anything about it and claim I can't of saved anything. I did save everything but it now appears its gone regardless and all Admin could suggest is I start again.
Has anyone else used this site and had similar problems ?
