Hi Klark, also if you're running the v3 beta there is a bug that can cause it to be confused about the expiration mechanism, it's somewhat hard to trigger the bug (it involves running a previous beta at a certain time of the day near midnight right on the day that it expires), but that may be what you are running into. If it's that then also send me an e-mail at moi@moi3d.com with your license key and I can send you a tuned up beta version that should fix that.
