The error points to the `readKeyMap` function which sounds like it would be 
a part of the `filehash` package. I would check to see that you have 
read/write access to your metrics dictionary, `options( 
'tikzMetricsDictionary )`, and possibly try trashing the file so that it 
gets re-created. A corrupted dictionary could explain why several versions 
of the package are failing in the same way.
