The response and challenge always leaves a bad taste in my mouth. Though the reasons may not apply to CL as much as other small companies using this method. Essentially it goes like this: I install the program and it generates a new code and needs a new response. I contact the company and get the proper response. 4 years later I buy a new computer as my old one died. I re-install and it generates a new challenge code which I need a response for. The company went out of business so therefore my application is now useless. This now leaves to to simply hacking the application and vowing to never again use software that uses this type of protection, or if I do, hell just hack it to begin with, forget the company. Protection schemes like this should always be built with a crisis plan in mind, but companies rarely ever think they will be out of business. Any company that does this should build the patch with the application to disable this feature. Release this patch only in a crisis situation as when the company folds. Hoprfully this would never happen but it is always a possibility.
