When attempting to download an EPUB book from Pima County Library, I get the following message
Error getting License. License Server Communication Problem. E_AUTH_BAD_DEVICE_KEY_OR_PKCS12
Based on frontlinesupport at Overdrive, I have uninstalled and reinstalled in succession, ADE 4.5, 3.0 and 2.0. Always the same error message appears. Each version of ADE shows that my computer is authorized, but still the same error.
I've had no trouble for well over a year until October, 2015.
My laptop hasn't changed, still using Windows Vista Home with Google Chrome.
