Okay, try this:
From iTunes:
Click on the CraftLit title in your podcast list (assuming you still have a subscription. If not, skip to the next step). Go to the Advanced Menu. Click on "Subscribe to Podcast" A write-in box should open asking you for a feed. Type in: http://craftlit.libsyn.com/rss Click okay. You should see everything update right away.If this doesn't work, add a comment here and I'll keep working.
For those of you on other podcast aggregators, this information SHOULD also be correct for you. The feed itself never changed, but iTunes got glitchy.
Ain't technology fun!?
