Hi - and many thanks for the advice.
I’ve removed the files as you suggested, and can now see a human figure when I click on any of the ‘Basic’ models. Progress! (It sounds daft, I know, but I think I was more excited than if everything had gone right from the start! )
I seem to be able to manipulate the figure, in that I can get it to move around by clicking on those little arrows etc that appear around the body.
I can’t do anything else, eg dress the body with hair/clothes etc.
That may be because I haven’t yet done everything you asked me to.
I know I’m showing my ignorance - again - but how do I move the folder?
Again, many thanks.
