I have a small problem.
When I connect to my DM with any browser I get a screen saying:

If you see this, your box didn't boot to Linux.
Unless you interrupted the boot process, this usually means that you have no valid operating system in flash.
Don't panic! It's not a problem. You can just flash a new version and everything will be fine!
Otherwise, you can boot from network or USB.
If you're about to give up, you might get help at the Dream Multimedia Support board!
Currently there aren't many other features...

You can download your current flash contents (256 MB) here, but please don't expect to be able to flash it back. It's merely a debugging feature.

device info firmware upgrade"

I press on firmware upgrade and on the next page I choose the ssl8j.nfi file and press flash but nothing happens...
Any ideas???
Thanx
