Take the six screws out of the back, take off the face plate, with the button membrane in place and the battery installed, gently pinch between the right side middle Lcd panel and the back of the remote, if the screen flashes on and off you have a loose connection, if you can keep it on long enough, you can probably get into control panel and get your file out. I saw a remote do that once, I just put a folded piece of paper between the face frame edge and the lcd panel, remote still works fine after 3 1/2 years.
