Here is what happened:
I installed the latest itunes
Went here: http://www.japanesepod101.com/helpcenter/getstarted/itunesfeeds
Clicked the Basic Feed button
Allowed the browser to open iTunes and checked the "do not ask again" option
It opened iTunes, and asked for my username and password
I typed it and clicked ok (not sure if I checked remember password though)
Then nothing happened
Now everytime I click the Basic Feed button, It just opens iTunes but nothing happens.
I tried clicking the Sample Feed button, then it seemed to work. A little down arrow appeared on the top right corner of iTunes showing my download. But with the Basic Feed nothing happens.
I also tried reinstalling iTunes, but it didn't help. It didn't ask for my username and password again after the reinstall.
