I am using the trial version right now. I don't know what DV D43 is, is that something I need to download? Something else I just noticed, now that AnyDVD is unistalled, the computer is still freazing so I am trying to figure out what else could be causing the problem. When I start the computer up in safe mode, there are no problems so obviously something else is causing the problem. I just can't figure out what program it is.
