Honestly, don't people ever read EULAs? Or do they do the same thing they do with the Bible? Never read any of it, just scroll to the end and click on "I Agree." Seriously: READ the "warranty" on your software. Chances are it's a variation of this, which is a warranty stripped of its legalese: "We warrant that this package contains a CD, and that there is some kind of software on the CD. We don't claim that (1) it is what you need, (2) that it will do the job we claim it will do, or (3) that it will even run in the first place.
This is how software has been marketed since day 1, and it's the way ALL digital content is marketed. The best license I ever saw was the one that Borland International used: it was the same as a book: you could use the program, and you could lend it to someone else—just so long as there was no possibility of it being run on 2 machines at the same time. Back in the days of floppy diskettes, this was pretty simple: lend your buddy the disk, and you didn't have it. When he gave it back, you had it, and he couldn't use it.
Nowadays, even though the law says that you may legally make backup copies of your software or other digital media, copy-protection schemes frequently deprive you of that legal right—and it is ILLEGAL to bypass them to do what the law permits you to do.
