FIXED!!!
Ok, so here's my "fix".
I gave up. I've been trying to update it since last night. Tried it on 3 PC's. Different OS, USB ports, plugs, DFU, blah, blah, blah...
So I took it to the apple store. They had one guy just doing iOS updates. I told them my iPad was now a brick.
He hooks it up, places it in DFU and on the first try UPDATE SUCCESSFUL!!!
I don't know why, I don't know how, but he got it to work in the first try.
So, there's my "fix". Take it to Apple!
BACKUP BEFORE YOU GO! (assuming you could still back it up. Mine couldn't).
Good Luck!
