First off, if there is a FAQ, I will learn to use it but since I am new to this place and software I have a couple of quick questions. Yesterday, I upgraded my largely unused SONAR X2 Producer (itself an upgrade from X2 Studio) to SONAR X3 Producer. That got me 12 files to download, which I did and I have install (I think) aside from the Addictive Drums which I will catch after work today. My questions are these:
1. This came also with Dimension Pro 1.5 plus an expansion pack. I already had Dimension Pro installed from X2 Prod so do I need to install it again (IE has anything changed?)?
2. I see there is an update to this program called X3e (I believe)...where would I find that to download and install?
3. I have access to Lynda.com and with it a course called "Up and Running with SONAR X2 Producer"...can I assume there are enough similarities between X2 and X3 that this is still a viable course?
Many thanks in advance and I promise to be a good forum citizen once I get grounded here because bad ones drive me nuts too

My setup, if it matters is:
Windows 7 Home Premium 64bit running on a Sweetwater Creation Station CS250v21, an M-Audio Fast Track Pro USB audio device (possibly to be replaced one day by ?), a pair of KRK Rokit 5s, a Nektar Panorama P1 Controller (used with Reason - a lot), a Korg PadKontrol, and my keyboard is a Yamaha MO8 that is now basically a glorified MIDI controller -- but does actually make it's own sounds too :)
