Replaced the nozzle. Dual printing again.

As usual I was going to take a lot of picture and walk you step-by-step through the process i went through, but the Makerbot's support page pretty much covers it, except for the absolutely filthy state of my old nozzles. And when I lost one of the nozzles, just put it down somewhere and I lost track of it. I'll find it. The old nozzle got an acetone bath and something fell out of iot, probably the blockage, so I'll save it for the future.

But that's it, 15 minutes and it was done. 30 minutes after the leveling and adjusting and changing the Kapton tape. Easy peasy.
