602 locked Library

[Henri2all]

Hello,

I have the Pocketbook Pro 602 now for a few weeks, and I was very happy.
At last a reader that accepted most of my e-books.
Untill a couple of days ago.
I decided to put al my scifi book on the reader.
After I put them on the reader (not a card) I removed it from the PC.
The reader started normally, so I clicked the library, and then it happened.
It keeps reading the library, the icon stays on the library, it stayed there for more than 5 hours.
Turning on or off, ressetting etc. nothing works. I soon as a click the library it got stuck.
After turning on, every works, also my last open books, but the library is locked each time you click it.
I have removed all my books but even then it got stuck.

I tried to update the firmware ,I have the last version, but each time i get the message update is corrupt.

So that does not work either.

Please help!!!
