Sorry to hear about your log, I know how annoying it is, it has happened to me too a couple of weeks ago!
Altough I only have a PPL (yet), I too will get a "Sworn Affodavit" or something.
The CAA told me that one doesn't need all the signatures and the like, that's covered by the lawyer who signs your "affodavit". It sounds rather easy for frauds to me, but that's their problem.
However, I send them an e-mail asking if I have/can write my flown hours in my new log, because on the phone they said I shouldn't, I should start over from scratch. But I want a complete log! They haven't replied yet.
Suc6 in your efforts, it's a hassle!
