Just download the demo version. You can't save the design but you can take screen captures. I use the demo for all my scratch builts, unfortunatly the design has to be done all in one sitting but it's still a great tool. It's not that hard to use after playing with it a few times.

Back to your original question, the cardboard cutout method finds the LCP "Literial Center of Pressure" based on the outline of the object being modeled. Like Teflon mentioned there are some designs that are just to complicated to model accurately with our current MR software. PMC's of most aircraft is a good example, but simple 3f&NC rockets can be tested this way also. If is important to do a cutout of a side and top view of the subject if the model is asymmetrical, average the results to find the LCP. One view is fine for symmetric models.
Once you know the LCP of your cutout simple add a point a least one caliber ahead fo the LCP. that is were your finished models CG will be. add nose weight or larger fin area to adjust the models CG to that point.
Yes it is easy. If done with care, you will have a model with will be on the overstable side but very flight worthy.
I can't argue with that. If the price were half as much I might actually buy a copy instead of just playing with the demo.OH man I don't want to start this again.. Rocksim IS a wonderful, tho WAY overpriced MR tool.
