This is stunning and insult to injury Dropbox is a brick wall and provides no way to contact them for customer support.
I opened the files Saturday and was very confused to see only prompts for tutorials on starting using DropBox. There is nothing I perceive in deleted files, etc. I unfortunately had not saved my computer in past 6 months or so.
Very upset and shocked. There were interviews with a woman then in her 80s about her experience during WWII. She has since died. I also lost the last version of my book I based on her experience. Any help in restoring these files would be greatly appreciated.
