Help with crashing when unfreezing a device

Analog Dan's icon

Hello folks

Has anyone had experience with a frozen M4L device that crashes the MAX editor when it's unfrozen? I built a little synth to give to my students - frozen to include a couple of abstracted patchers and some images - silly me didn't save a copy before freezing...

I've attempted un-freeze on several different Macs but the problem is with the device it seems. Any insights would be amazing.

:D
