OK I went to load the ad but it wouldn't play because it's only US content. But it left the US store sitting in my window and I couldn't get rid of it. Anyway seeing as my iTunes is a virgin account because I've just reinstalled my whole operating system, and haven't imported my music back yet, I thought I'd just delete all the pref files and cache files, but I couldn't find any caches. Now I open up itunes so it's like it is when new but when I start to modify it like delete a default list, iTunes crashes. What should I do to fix this, and how did it get broke?
