There is no time limit or fancy licensing associated with InstantCake (or any of our utilities).
Many of our CD's (if not all of them) will automatically send the user to our web site, once the CD is burned and inserted in to a Windows-based computer. This isn't intended to confuse people, just get them over to our site should they stick the CD into their system.
Hopefully, you found your way to our forums for support
. Disregard all the noise and repetitive questions there - there are basic instructions, and release notes at the top of the tech support area; those should get you on the right track.
Thanks and good luck,
