Hello, I have recently installed puredata 0.53. I have loaded many of the externals that I have used before and I've had no problem accessing them. However the CEAMMC external is not working. Specifically when I add it to the startup menu and restart puredata the puredata crashes. When I start up puredata again it tells me that it is not loading preferences and that I have to save preferences and restart. If I remove the CEAMMC line from the startup the error disappears. I still cannot use any of the items in the CEAMMC external however. Here is the info about my Mac system:

Here is the core dump from the Mac:

Am I doing something wrong?
