Today, I copied FW2.0RC2 to a clean SD-card. I booted the DR1000 to reinstall the firmware. After the "upgrade" completed, I safely removed the SD-card, inserted it in my PC and copied Pauli's MHT file to the SD-card. I safely removed the card from the PC and inserted it in the DR. The DR did not show the MHT-file. Not in Personal Documents, nor in the SD-card browser.
I also tried renaming global.db. That didn't help either. I am really clueless

what is going on.
PDFs and ePubs work fine.
