Go to Droid X SBF and download the files for your computer. Then you will need to go to Complete Droid X .sbf Flashing Guide - Droid Forum - Verizon Droid & the Motorola Droid Forum for the directions. It's not as hard as it looks. Just follow the directions and you'll be fine. Same thing happened to me the first time I flashed Liberty GB. I would just load bootstrap through the Liberty toolbox when you get back up.
