Hi ,
Thanks for your advice
Here are the files
biab_plugin_crash_files ( I have not found files BBREsults.txt and BB Song.txt) , and the EventWiewer trace.
Before the error , I was able to generate about twenty generations of the same song in a row ( without playing it)
The WinDbg.txt file was made by attaching WinDbg to Reaper_Host64.exe process (but not in the same session as the files above)
