Just an idea...

Well, it can't check your cd-key just like that, but you need a valid cd-key for the version you are trying to use, because clone-cd usually will start with a banned cd-key, but it will ruin the cd-r when burning something.. Disable the "check for updates" in options.. Then if you have a working key, clonecd can't check your key (unless you install a new version later)
