I am "assuming" the OP is a copy of SONAR X1 LE. IIRC, that program did not have updates with it, so may be troublesome, especially being a new user.
My recommendation would be to register SONAR X1 LE so you qualify for discounted upgrades, then look into something simpler like
Music Creator 7 (I believe is $19.99 as an upgrade). This has the same audio engine as the newer SONAR, just not as many features (which being new you would never miss... yet).
As far as tutorials, google is your best friend, and is easiest to start with tasks you want to do (keep them simple at first). The "Get Started" link under CakeTV on
this page is also a good place to start.
Also, if you want to search the forums (which is full of useful content), is easiest to use google and preface your search terms with "site:forum.cakewalk.com" in the search box.
