I download books from library and program worked ok for long time. Now, it freezes when I open it and click on any option. I have uninstalled and reinstalled several times to no avail. Tried going to 3.0 version and got activation server error code: E_Adept_internal. I have Windows 10 now, using Edge as my browser. Used to have Windows 8 and had IE. No errors found from left over software when I cleaned the registry. Any solution suggested?
