Inconsistent Signing Key

I know this has come up before, and believe I've done all the standard things to fix it:

3/5/2016 3:40:33 PM      [error] Inconsistent signing key from account manager

 I have had multiple accounts in the past, but I have also uninstalled the GR account manager, rebooted, deleted any BOINC folder search could find and then opened a new account, reinstalled, and get the same issue. How do I fix this?

Many thanks indeed
