Can't reach keyserver - "host not found"

I've been happily using Trinity for a couple of weeks, and needed to reinstall it after changing distros -- but the GPG keyserver (command copied from instructions) is coming up as host not found. Here's what I get from a nslookup: Server: 156.154.71.16 Address: 156.154.71.16#53 ** server can't find keyserver.quickbuild.pearsoncomputing.net: NXDOMAIN PS. Thank you (to anyone working on the project) for creating, working on, and hosting Trinity. I first installed Linux in Spring 2008 and KDE 3 was what made me fall in love with it!
