Tivo just deleted almost half of all my shows. Upset

I was trying to move a 2 hr tivo show back from my PC back to tivo using tivo desktop software. At this point my hardrive capacity on Tivo was at %90 full. I tried to play the vido from my tivo while it was being transfered and I would only get audio. I know tivo roamio on my gig network should be able to transfer fast enough for me to watch real time so I knew something was wrong. I stopped the transfer. went back to my shows list and now my capacity reads %70 and a ton of my shows have been deleted and in the recently deleted folder there is nada! WTF! Anyway to get my shows back?:(
