I installed OSX Yosemite and Adobe Digital Edition 4.0.
Since then I cannot import new books (from Kobo) and I cannot see anymore the books, which I bought earlier.
The error message is:
Error getting License. License Server Communication Problem:
E_ACT_NOT_READY
I tried to solve the problem by de- and reauthorization.
However, this was impossible. The program did not recognize my password. A new password did not help.
