Some notes before we start
RazorBlade can be installed as a stand-alone DNN module or if you are creating your own module, you can include it in your distribution. 2sxc 9.40+ includes RazorBlade 1.01, 2sxc 10.06 includes 2.0 and 10.09 includes v2.02. If you see errors, you probably need to install a newer version of RazorBlade.
Your RazorBlade version is 4.02 - which is what you need for all these tutorials.
