Failed to Open Model

[JacksonLane]

I'm working on my model in modelbuilder when suddenly ArcGIS freezes and crashes.  When I open it back up, I get this error message when I try to open my model:

I've tried copying the model, moving it to another toolbox, and using a different computer.

How can I recover my work?

Try naming the toolbox and model something other than "New Toolbox" and "Model", and put it on C temp, not on a network share. I have a hunch here.....

I  still get an error after copying to my Default toolbox on my C drive.  I can open other models on both my network and local drives.

I know of no tools that can recover corrupt tbx files (along the lines of MXD Doctor).

This is the solution??
