"My Feed" keeps changing!

[Gudrun]

I initially set up a "My Feed" in Koreanclass101.com and basically selected to receive everything and gave it a name. But every time I go to iTunes the My Feed has a different, random name. And in the past week, My Feed won't download the most recent lessons so I had to also select "premium feed" so now I have 2 copies of almost everything on my computer except for the last week's lessons which will only download in "premium feed." I totally don't understand why My Feed has been acting strange. It's been changing the name every time I log on since I started but at least it would download everything. Now it has stopped doing that and I don't know why. Anybody else with strange My Feed problems? Help!
