Hello,
I have a problem with a protected pdf. I just bought an ebook to read it on my Onyx Boox 60 which is supposed to be supported and support adobe digital editions.
On my PC, I can read the book on ADE: everythings fine.
I can copy the book to the Onyx Boox 60 from ADE interface, but when I want to read it on the e-book:
I get the following error message:

Cannot open the document.
E_ADEPT_NO_VALID_LICENSE

I do have authorized both my PC and boox.
Then I deleted the pdf files on my boox, and when I tried to re-copy the files from PC (using ADE), I get the following error:
No permission to copy document here

Has any one get idea how to solve this problem? I suspect this is related to proper authorizing my boox, but I don't know how to do it.

Thanks in advance,
hans
