Updated Sansa firmware, now no Rockbox?

[AFinekerfuffle]

Hey there, I seem to have run into an issue.  After problems  with writing playlists to my Sansa in usb mode, I updated the Sansa firmware to it's newest release. This fixed the problem I was having, but seems to have brought up a new problem. Now when I start up  the player, it does not boot up as Rockbox but rather Sansa. (as if Rockbox weren't there) The Rbox version is the most recent one, running on the Sansa e280. Let me know if  I need to provide any further clarifications.
Thanks for your time!

When you install the original firmware it erases rockbox.  Reinstall rockbox.
