Digital Access Question "Modern U.S. Armor"

Hey FineScale,

If I buy the Digital "Modern U.S. Armor" and I download it at my work computer, can I then put it on a "stick" so that I can use it where ever I wish, like on my home unit?  I'm not a computer wizbang but I know sometimes these things only download once or have some magic protection on them.

How about it guys?

Thanks,
Dennis.
