Annoying iTunes!

I am very upset at the moment... Our iTunes store isn't working which means I can't buy any new songs and over a month ago I got three gift cards all together equaling $60 and I can't spend it since iTunes won't let me access it unless we download the latest version, which we can't since my foolish mother passworded our computer against updates. We have another computer but it doesn't have sound or iTunes.... So quite upset at the moment also I have found an album and so many songs that I would kill to have on my iPod but have to be content to just wait until mum miraculouly remembers the password or we get a new computer.... I may have long to wait.
