not getting processes to work on SoundLoom through CDP8

[lukelewis]

Longtime user of CDP7/Soundloom here and have been using it perfectly for years after Trevor Wishart taught us it during my masters year. I'm on Mac 10.13.6. Installed CDP8 and everything looks good on Soundloom until I get to actually doing a process on a file. I can play file on workspace but when I go through and click on a process (ie. 'distort','radical' etc.) nothing happens, no window for the process appears as it normally work. I'm pointing to the correct _cdprogs within Soundloom but a bit at a loss otherwise.

Any help very gratefully received as I was hoping to teach the software to some undergraduates this term! Thanks.
