Wondershare PDF Element took over a Word document I had spent hours working on. The Word document was just gone, replaced by a pdf doc that I had open. Spent 4 hours trying to retrieve the Word document with no success and finally had to spend 4 hours to recreate it. I was scared it would happen again so I deleted the program from my computer. When I finally reached someone in customer service they said they can't help me because I don't have proof of what happened, and refused to provide a refund without that proof. I am deeply disappointed in this product.
