Empty AppleTV Menu after install atvflash

Successful installation, reboot automaticly after the AppleTV Menu only EMPTY box. Only the apple symbol and “tv” on the upper horizontal box, and two vertical box under it totaly empty. No menu at all.
I try to REINSTALL the aTVflash -it was successful- but after no menu either. BTW I can see in the Network AppleTV (has IP number) even I can reach the folders via Cyberduck ftp. Now I copy on movie to the /Movies folder. I do not know how to play back without AppleTV menu?
Please help.

This sounds eerily familiar to my problem. I only get the Couch Surfer in my menu with all other options gone.
