Two immediate potential problems to resolve are the space in the path name at "ben poole", and the combined length of the grid filename and its path being potentially over 128 characters at any stage in the processing. Since the process is using an ESRI GRID, it has to meet very specific file and path-naming conventions, which are much more constrained than for other data types. I'd start by fixing these, as it often seems that these grid issues also spawn other unrelated errors.
Esri Grid format
The name of an Esri Grid format raster has more specific restrictions:
- The maximum number of characters is 13.
- It cannot have spaces.
- It cannot use special characters other than underscore ( "_" ).
- For tools that output a Grid Stack, the stack name cannot have more than 9 characters.
- The total length of the name for a Grid and its path cannot be more than 128 characters.

Bear in mind that these constraints applies to the folder names also. Having just one space in a folder can cause things to go awry. Note that their is no specific error that will come up alerting the user that the issue is due to a space being present.
Also - not a hard and fast requirement, but can help - stay away from the /Users/username structure if possible. Try to use a very short, direct path to the data, like C:\Data\Model or such. In theory it should not matter, but in reality sometimes that can be the difference between an operating process and one that throws errors.
