You could try the following - they are both to do with the settings for the
"decimal separator" in regional options, which could explain why only one
machine is going wrong:

When I enter any field with a formula (example subtracting
a number from NUMPAGES), the result of the formula is

!Invalid Character Setting

This happens one one machine only - the same document
gives correct result when opened from another machine.

Any ideas?
