Scrapbook Factory Deluxe "Evaporated"?

I ordered this software through amazon.com and shipped via vpost.Got the newer version than what's available in sg, and at much cheaper price.

Wanted to install on my notebook, but couldn't find it anywhere in the study room,the whole box with software just disappeared?!

The last time I used to reinstall on home PC, it's just this year, and I never had to bring it out of our study room.

There were very few people who had entered our study room this year, may be 4? and that's including the air-con serviceman. I just cannot figure out why it would "evaporate" ???
