Wasn't sensitive enough to, right? A 'no call' means that the chip wasn't sensitive enough to detect that particular SNP. 'Not genotyped' means 23andme did not intend to check for that SNP - it isn't one of the ones they look for.
@Gondwanaland , @pogoman : I did download the analyzer you suggested. The only thing I don't like is that they mention the same SNPs over... and over... and over again. I understand that they want to group them by health issue, but I'm doing research and I find myself looking up the same ones again and again.
