Yes, the LMI free version cannot be used in a commercial environment. You must upgrade to the pro version. Ironically, it is commercial when you access a commercial computer either commercial to commercial or private to commercial. It is not commercial, and therefore does not need a license if you access a private computer from a private computer or a private computer from a commercial computer. So, in short, you can't access a commercial (business) computer with the free version of LMI. I don't think I could have made that any more confusing, hence the previous sentence.
