When you receive the new Creo license, you also receive access to some of the tutorial. I susgest you work thorugh the "upgrade" and "enhancement" tutorials to egt a good overview of how to work with Creo.
You should also have access to the learning exchange:
http://learningexchange.ptc.com/tutorials/by_product/by_product/page:1/product_id:1/url:tutorials
And last, if your system is set up correctly, you have access to the learning connnector. If you click on the little home button in the connector, it will bring up a lot of tutorial videos.
