Do Alf's deDRM plugins need to be reinstalled when Calibre is updated? I ask because I did install Alf's stuff once but today I saw a DRM error message for a just-imported epub file and I do not see Alf's stuff listed as installed.
P.S. Actually, Alf's plugin is listed as installed in one place and not listed as installed in another.
