I can't reinstall Rockbox (PPI NAND ??)

[gabee310]

Hi ! I have a problem... I installed Rockbox yesterday. I tried it but I pushed a button and after that, I couldn't see the letters to arrange it, but I couldn't. So I uninstalled Rockbox with the recocery mode and it works now :-)

But after, I wanted to reinstall Rockbox but I can't. When I connect my sansa e250, I go on "My computer" and I can see "Sansa e250". When I click on it, I can see "PPI NAND" with 1.84 Go. And when I click on it, I go in the file where you can see MUSIC, PICTURE, RECORD, PLAYLISTS...

But when I try to install Rockbox, I think I can't because the "PPI NAND" is there...

Thank you to help me !! :-)

It's okay I found it... I just have to put my sansa on MSC mode ^^
