Serious Difficulties with Exporting to a wave file

[JohnHipHop]

I am using Mulab 7 (7.2.23 64 Bit) and have created a basic project with 3 tracks and as a fourth track I have a plug in, MDrummer. In Edit mode or Compose mode (where I have selected all parts of the track in each track) when I go to export track to an audio file only one or two tracks are saving on the wave file. Even if all are selected. There appears to be no mixdown from file as in older versions, for the Plug In, only an option to select the track. Even once it is selected, it will not export to audio as a consolidated file. In fact the current saved wav file is only of the Plug In, and now when I got to export composition as audio file, it will not export the project. The tracks will not export as audio files either. As I have managed to export the plug in then this must have carried out a mixdown but it will not export with the other tracks. I did render the selected parts/new parts as a sample, but now I cannot located the sample itself, as when the pull down menu shows it does not show the files themselves, only the names in the pull down menu. This is all a huge headache, even though the music that has been made is a good track.

Does "Project -> Export Composition as Audio File" not work for you?
