Error message turning on
Is it possible you deleted system files along with other files by mistake?
It's a very common problem, and it would be good to know what causes this since some people say its because the Lyra allows you to delete system files which screws the device.
I heard of someone that called Thomson helpline with this problem and got his replaced, so it wouldn't hurt to try.
RCA has this page on the problem: http://www.rcaaudiovideo.com/Cultures/en-US/RLDetail.html?ArticleNum=112&PC=
It might help...
And there's this program that is said to help with the formatting, get it here along with some instructions: http://www.techolio.com/rd2780_upgrade/
