The WB does not appear to recognise the two add-ons as separate files. For example, I uploaded the Back Compound file; however, it now won't recognise or import the Chest and Shoulders one. The message I get it 'You have already uploaded this file!' and so the WB seems to think they are the same file. I've downloaded them all again and I still have this problem. (I am definitely not trying to upload the same file; I was careful to check this). Thanks for any help you can give. As before, Vista 32-bit.
