if you used it on your computer b4, you can do this

but after it expired, be sure to set your system time BEFORE you open becker!
From what you said, I guess you borrowed it from a friend or something. I suggest you do a normal install, as long as you don't register with becker online, there is no way for them to know how many times you install the master CD. (they count online registration for three times) I'm not sure about the lecture part, b/c I never watched it, the lecture is very useless. But i'm pretty sure if you do a normal installation of master CD, you can use all the data CD's that are attached to each book, you can do multipul choices questions, but you can't open simulations.
