I have several Solidprofessor instructional videos, and am more than pleased with them other than the fact that only two installations are allowed and if you have a hard drive problem or have to format your drive for any reason, and have one installation on your desktop and one on your notebook,well you can guess the rest. If someone here is familiar with the I get it instruction system, I would appreciate an answer to the following questions. 1. what do you think of the quality of instruction? 2. is the format comprised of both audio and video? 3. what are the licensing restrictions with regards to amount of installations allowed. I will thank anyone who responds to these questions in advance, Gabe Pacheco
