Hi I have looked up this subject and found a post way back in 2013 and yet cannot find any satisfactory conclusion. I also have exactly the same problem, I am running NXT Pro2 (Build 150B05D). Attached is the DxDiag.txt with all my computer information. Please can somebody advise me how to overcome this problem of adding more than one track to my videowave project.
The Add Background Audio selection box has now locked up and wont allow any navigation or selection of music. I have rebooted and done a little dance and waited, guess what still nothing. Can someone please help.
