I have used ADE for years to borrow books from my library & drag onto my Kobo Clara but over 12 months ago it gradually deteriorated & eventually failed completely. I have tried everything recommended by Adobe, uninstalling then reinstalling with different versions & using different browsers without success. ADE appears to download ok but when I try to open it the logo appears showing "Loading Library" - I have let this run for hours but nothing happens, it just hangs there attempting to load. I have had my local computer techs look at the problem but they could not solve it. I am at my wits end & am ready to give up but thought that maybe someone might be able to help. It sure would be appreciated, thanks.
