No, I'm afraid not. Although, looking at the post again has reminded me that I was on BWS 3.3 b2 back then, and I am on beta 5 right now. I've just tried again, but sadly, the plugin is still crashing if I try the Bigwig method of loading presets, and I still cannot work out how to load a preset manually. I've explored every square nanometer of the Ribs GUI and I've tried dragging the preset from Finder over Ribs. Nothing seems do anything :-(
