Help!!! My baby!!!

I was trying to Customize the Fonts on my PRS-505. i followed the instructions for the Customizer and copied the Files to the SD Card.
My pervious Flashes have worked just fine, but this time. It began itz
reboot, and then rebooted again and again....
I downloaded the PRS-505 Updater and edited the PRSVersion.dat file.
I run the Updater, i get please connect PRS-505. the update button is
sorta greyed out and it obviously doesn't click to begin.
i can access the reader as a disk drive but thats all. i tried reinserting the
SDcard but the reader just continues the cycle.

Any help would be greatly greatly appreciated!!!
