This depends on the exact commands that are being used in your .do file,
so it is hard for us to say what this might be without seeing that .do 
file.

You could try to precede your .do file with:
set traced 2
set trace on

This will give you lots and lots of output, but you only care about
the lines immediately preceding the error message. That gives you
the command that returned that error, which sometimes helps in pinning
down what the problem is. (The -set traced 2- reduces the amount of 
output, if you need more output you can increase the number of leave 
it out.)

Hope this helps,
Maarten
