Perhaps I'm missing something obvious and someone can help. I purchased CVData/CVCX a few years ago, and after reformatting my computer last year, had not yet installed it. Trying to install it now (Windows 7, btw), I can install the demo, but when I attempt to unlock it seems to not work correctly.

I don't have the CDs with me. How do I download the most up to date version, and unlock it using my license number?
