Well, if anyone screwed up (like me

) and created a new key after the ADE upgrade, there are several comments on the cabbages blog on how to fix it.
There is a link to download the old version, to uninstall the new one and go back to the old. Reauthorized your PC and create a new key. I've just been putting up with the 'upgrade in 44 days' box, but I can deDRM again.
Whew! I have a backup or 10 now!
