Error downloading *only* Reasonable Doubts podcasts

Is this just me?
I haven't been able to download any reasonable doubts podcasts for weeks.
In the interim, I've even reinstalled my operating system (to Win7) and reinstalled the latest version of ITunes - and still *only* Reasonable Doubts podcast fails to download (of at least 10 others. larger & smaller, which continue to download fine)
It happens after downloading about half-way, sometimes almost all the way, with error "-3259"

I was posting, not for technical help, but to confirm this is not a problem at the source?

I used to have this problem and I'd have to manually download each episode. It doesn't that anymore, so I just assumed it was an itunes hick up among millions of others

Sometimes I used to get this problem with other podcasts on iTunes and not just with RD but I haven't gotten this error in awhile, so I also agree that it might be an iTunes problem.
