Hello Everyone,

I'm very new to IntelliJ IDEA, and  I'd like to learn all of its features.  My company has licenses for  version 10.0.3, and also the Manning book "IntelliJ IDEA in Action", but  the book is several years old and several versions of IDEA behind, so  it's difficult to work through with my version.  I had the idea (no pun  intended) to download and install version 4.5.4 on my home PC and work  through the book with it, but I wasn't sure if I could use my work  license on the older version.  I suppose I could just go ahead and try  to see if it works, but I wanted to see if I could get any input here  first so that it might save me the hassle of having to immediately  uninstall it.  Any constructive input would be appreciated.  Thank you.
