Adobe Digital Editions 4.5

I am trying to retrieve my Digital editions, which I bought from, Takealot, they are there on Takealot to Download but I just cant get them back into Digital Library on PC. I lost all that was on my PC some years back when my PC crashed.  I had to buy a new PC, so I don't have an Adobe ID for digital editions anymore.  I paid for these books at Takealot , a South African online shop.  They show there in my library, but can't get them downloaded onto Digital Editions Library.
