iTunes is a bitch. Remember how I gave that little instruction about going to a web site and clicking launch application and shit? That doesn't matter... not if you do it on Friday.
Here's the deal: the iTunes store is "inaccessible", apparently, on Fridays. Same thing happened to me again this Friday, and I thought, that's just weird, the same glitch two weeks in a row? And I tried going to the phobos.com web site, but it did nothing, it didn't help. So I got up on Saturday morning and tried it, remembering that it was on a Saturday that I got it to work last week, and lo and behold - iTunes store is right there. Whaddya know? I have no idea why this is - if iTunes does maintenance or something on Fridays or if my computer remembers that I installed iTunes 7.0 on a Friday and is holding some kind of anniversary vigil of silence, who knows. So if it's Friday and you can't get to the iTunes store, try on Saturday.
End of post.
