I' having problems with the AUTOBOOT / File Selector..

My HxC works just fine with normal use; Selecting the files from the HxC display, but auto-boot function freezes in start-up.
It boots up and goes to the "welcome" menu, but then a long beep is heard and the message "DIRECT ACCESS LBA:00000000 08" is displayed.
Then the menu is frozen...
I have read the manual several times, and updated the firmware to newest version, HXCFE_V1_8_2_40, using a freshly formatted FAT32 SD-card.
I've tried formating the SD-card again with brand new downloaded AUTOBOOT.HFE and brand new HXCSDFE.CFG setup to auto-boot from default.
I've tried running the card with the prepared files from the download site, containing the Arte demo.
The HxC itself has the buttons extended, not the original ones, but from the place that is given to do so.
The display is also extended. But unplugged or not, still the same problem.
Please help me!
How do I correct this?
Thanks,
Troels
