PDFs not readable
I have strange problems with some pdfs and my Clara HD. On my Mac the info panel of preview tells me the pdf(s) is/are not protected. I can use them as expected directly from the file system.
When I try to open them on my Clara HD, a window popup tells me they are protected by Adobe DRM and I should activate my reader.
My Adobe ID ist activated, I logged out and in again, it didn't change anything.
What's wrong here?
