difficulties for a newbie!

edit

Hi- I am trying to do the first exercise, opened " SketchUp" : 1- the select is too slow! it takes more than a min to select any element! I don't know what is wrong. 2- I understand the difference between my version ( installed everything last week) with the tutorials that I am using (2012), however, I should be able to find them in my version! for example , these basic tools: -New Zone Tool -object info tool I couldn't find them to even finish the basic example! appreciate any advise or comments you could offer. thank you -Fatemeh
