Nero Vision 5

When trying to load a file to burn using the above I get as far as selecting the file and loading it to Nero vision when the program just switches itself off and I’m left with the desktop. I have tried uninstalling Nero 8 using the Nero Uninstall tool and then reinstalling with the same result. For the last month I have had no trouble using Nero apart from the audio being slightly out of sync with the vision, and this problem has suddenly appeared.
At the moment I’ve no idea how to get over my problem and any suggestions would be greatfully recieved.

sorry the title should read Nero 8
