I have Imgburn v.2.5.5.0 on my computer.I wanted to burn an iso image file but accindentally I checked the box "Test mode". After 3-4 seconds I quit (I understood the error).But now when I try to burn that disc with Imgbrn it says "Disc not empty". I know that I haven't write anything on it but how to overpass this message.Any help will be wellcomed.Thankyou.
