hi there,
@cdp team:
i am using snow leopard and have been a user of cdp6. with cdp7 i have the same invalid data message (Cannot open output file cdptest0.wav) like NickFive.
@NickFive:
you are on mountain lion, so did you read the part of 'Release7-InstallationNotes-MAC.txt' which tells you about "Installation on Mountain Lion and Mavericks..."
and the 'Manualconfig.pdf'?
as i am having the same issue on 0sx 10.6 i doubt it, but maybe this could work for you..
