She said it is an Adobe problem and that Adobe is working on it. I asked her how did she know that, was the bank in dialogue with Adobe? She said no, they just went to the Adobe site (probably this thread!) and saw where Adobe said they were working on it! She said it is happening because the file is encrypted. I asked her why then does this work ok for my other bank, surely they encrypt as well. Here's where I should have written down exactly what she said. She said something like the other bank probably used different encryption like SSL (?) but this bank changed away from that because it got hacked. I can't recall what type of encryption she said they used.
