Hi Søren, I'm sorry, but real life has been a b***h lately, so I haven't been able to find a solution yet
I've tried looking at the files as recieved by both t iPad app, as well as the windows program, and I'm no where hearer a solution today, than I was when I started
I've had a look in the dependencies of stuff, and all I find is some weird propietary encryption, and that's unfortunately not what I need, to be able to decrypt anything
There is however a shimmer of hope (albeit a rather small one)
When you read a page, that page is then decrypted, so - in theory - you could flip through the book, and - manually - copy out every single decrypted page - and it should be possible to run them through calibre and get a readable book out of it - but it's a bit more work than I would prefer to put in to a single book...
oh - and happy new year guys
