I downloaded a locked pdf file. It actually ends in pdc, and unlocks only with Locklizard software. Anyways, I put it on my Kindle and it doesn't even register. I'm almost certain it's because of the lock. I tried googling the answer....tried many ways for hours, and now I'm giving up. I would like to use on my kindle because the book is huge. Can anybody tell me a way to do this...pleeeaaasssee???
