Hi, I´ve been having a problem with a Divis card I just bought. I installed all as the user's manual says, I set the space for the DB, but when I try to set the cameras they don't show up at all. The camaras are working properly, because I tried them using a converter to see them working on my TV. And when ever I try to run DVR Main program I get a message that says: "Overlay fail to open" and then it closes itself... Any ideas? Thanks for your time.
