I am attempting to use the areal interpolation option in the Geostatistical Wizard to interpolate 2011 Greater London output area classifications into the 2001 boundaries.  I have attempted to move through the four steps of the process on five separate machines, without success.  After pressing next after having selected the source dataset and field, I receive a message informing me that Arc has shut down and an option to report the error to ESRI.  Is this a known glitch? Four out of the five computers used never have problems carrying out tasks in Arc 10.1.  It may be important to mention that my dataset is quite large (25000 polygons), but I wouldn't think this would be a problem for 10.1 to handle!
If anyone has any solutions it would be greatly, greatly appreciated!
Thank you
