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?
Press CTRL + SHIFT + D. Then you get a proof if want remove and accept this.
