problems with the menu

[fastuco]

the problem is not just mine I read in a forum "friend" someone who has the same problem. I forgot to tell you that if instead of using the keys left and right use the up and down buttons on the receiver display shows the message that I'm going on the menu and if I press ok then lets me in, but on the TV monitor remains firm to hdmucenter.

Hello everyone I do not know how it happened, last night when I got home I turned on the receiver and the menu and return to work, but I do not read more than the pendrive. I currently use the pendrive for data only Epg of CrossEPG if I go to configure the cross epg me only the internal flash.
