Thank you for your input. This is what I did:
I downloaded a new zip with config+images. Deleted all on the config and typed: format (with notepad ++). I reflashed after a reset on the back with it on the MC, the CF and the USB (just in case; but I know only the CF should work). The same result every time: I started out with a frozen screen (picture of books iLiad etc on it)-when I tried to reflash the screen refreshed a couple of times and remained frozen afterwards. I tried it fully-half andcompletely decharged. I'm open for every new idea.
