Replacing Adobe account

For some reason My ADE authorisation went down and I was unable to get it back. I tried all the solutions offered in the forum which I thought I could manage (not the Regedit) but nothing worked. I therefore took the nuclear option and opened a new account which authorised the computer with no problems. This appears to have overwritten the old account. I find that my ADE library is still accessible, but I am not sure of its functionality.  Will the books in the library still be accessible for download to Calibre from the new account. Will the new account effect the ability to transfer existing  books already in my  Calibre library onto my reader. Kobo tell me that there should be no problem with new purchases and they say they will reset my DRM settings. My ebook system involves Windows8-Kobo purchasing-download to ADE- transfer to Calibre library- transfer to SonyT2 reader
