keep getting this error when I am trying to download ebooks from my public library (using mac version digital edition). I tried to de-aurthorize however it kept saying that it could not be done at this time. I also tried to uninstall digital edition and re-install with no luck. Plus I tried the steps from the online help and can't seem to find the file users//library/applicationsupport/adobe/digitaleditions. Any help would be great!!!
