E_ADEPT_NO_TOKEN error

[sasjal42415945]

I have downloaded the Adobe Digital Editions 4.5, the only way to be able to read my bought eBooks.

I bought several eBooks (from the same website, in ePub) and with most I had no problems.

One of them however gives an error:

Problem with the license communication. E_ADEPT_NO_TOKEN

Can anyone give me instructions how to solve this problem??

I paid for the ebook and would really like to be able to actually read it!

Correction on the above; I bought the books as an URL ACSM- link and they were transferred into ePub by Adobe.

Except from the one that gives the error when I am trying to transfer the ACSM into ePub. So because I only have the ACSM link from this book, I can't read it in any way.
