You could delete James casual and load the other james from the Figures folder and your morphs will work. You can then go to the props folder and use the James clothes that are conforming clothes.

A good tip would be to open P6 and then delete james casual. Delete the lights and add one white light and arrange your window to the size and lay out you like. then click on one of the UI dots to save that.

Go to Edit > General Preferences > Misc and uncheck Use external binary morph targets, uncheck Check for updates and check Use file compression which will save your files at a smaller size. Don't check it if you want to hack the files but they will be much larger in size.

Interface select Launch to previous state. > Document  click on the Set Preferred State button. Then select Launch to preferred state and change the Max cached renders to 1. There really is no need to save so many renders in poser. better to save out as a tiff to a folder somewhere else to use in what ever paint program you have that uses alfa channels. Hit OK.

Your P6 will open and run a bit faster for you and then you have a blank basic scene to start with.
