So to confirm, are you seeing yellow BB messages in the bottom right corner of your screen? Which style do you select that causes this? Have you tried with other styles? I would like to try recreating your problem on my computer so I can determine what exactly it is that's preventing the tracks from generating properly. It would be great if you could give me the steps (with details on what you are selecting) so that I could try the exact same thing on my end. Also could you go into your C:\bb\ folder and email me (aguy@pgmusic.com) the "bbinput.txt" file that is there? It has to be immediately after the generate crash happens, but that may help me narrow down the problem. Thanks Stephan!
