deactivation

[Guest]

I downloaded Adobe digital edition for my e-book studying.

But when i activate my computer, i made a mistake.

I had to choose campus e-book store as the eBook Vendor, but i did not choose that.

So i cannot open my e-book.

I want to deactivate my computer, but there is no button to deactivate. What should i do?
