Help! Sansa not loading!

[Packin]

I can't get my sansa to load, or get my computer to even see it as plugged in. It just keeps loading the black sansa screen over and over and over. I tried taking out the battery, but it's not working.

I uninstalled rockbox via the rockbox software, to reinstall it. I think that in the process, it also affected the sansa bootloader. Is there any way to force-boot the sansa so that I can reinstall rockbox, or do something to get it to boot?

I have the sansa e270. Thanks!
