System configuration? As far as I can tell, and taking into account my other programs that use a registration code assigned to my computer, configuration has nothing to do with it. I can move, secondary and tertiary hard drives, zip drives, CD-Roms.... anything - it doesn't affect the programs requiring a registration code. I know that Lightwave and Onyx TreePro run fine no matter how I change the configuration. I am not completely sure but I doubt that the CL protection is any different. I may be wrong, perhaps we should ask CL to clarify? "That is likely true for the majority, normal people with one computer, which is a desktop, and on the internet, and in the USA... Not everybody is like that." And what do these people do with other programs that require that sort of start-up? If they're serious about using the program then they will "bite the bullet" and do the extra work. I don't like having to do it either but it is a fact of life. Perhaps we should ask CL to have a toll free number to register for those who do not have internet access? That would solve that particular problem.
