Problem with Itunes

[HollyThirtyFive]

Basically none of the hotlinks work on itunes so I can search for music, see what they have but cant look into any options, although it did let me click on buy (suprise suprise!)

That was ok, until my debit card expired, which it didnt register until about a month after it expired and i bought some songs, so i am now "in debt" to them £2.37. I want to change my card details, but ofcourse i cant when the hotlinks donts work.

I thought downloading the recent version of it would help but when i install the set up it comes up with the message "error with the e:/ drive" then it sends up the message "itunes encountered installation problems so we cant install it"

Any idea what i can do?
