Theo,

I'm guessing that you have a trailing space in the first line of the polyline file.  I tried adding a trailing space to the first line of a polyline file and running it through the Gen-Poly-Mask tool,
and I saw the exact same error message -> NetCDF: Name contains illegal characters

So edit the file UAE.poly by removing any trailing spaces from the lines, and try rerunning it through Gen-Poly-Mask.

Thanks,
John
