I'm having an issue with the following code. The error is an undefined control sequence, the contents of the file does not matter on whether or not the error orcours. The error only exists on 1 computer even though the files are identical. I would very much like to know what could cause an error to exist on one computer and not another one even though the files are identical.
The error is as following:
LaTeX Warning: You have requested, on input line 235, version
`2011/05/13' of package alphalph,
but only version
`2010/04/18 v2.3 Converting numbers to letters (HO)'
is available.
