Hi I wonder if there is a genius out there that can help me out? I have recently updated all the new parts, but now in the selection window I have at least 2 of everything? But what is troubling me more is that nearly all of the parts I select won't snap together!! Is there a setting that I can alter to resolve this issue? Please note that any help needs to be easy to follow as I have messed up the program lots of times trying to follow advice! When I said that I have downloaded new parts, really my daughter has done it for me as again I struggle with these things, so advice on downloading parts ( in simple English ) would also be gratefully received 
Thanks in advance for anyone patient enough for my simpleness
