My I tunes store is set up for Uk purchases only, how can i turn this off now i'm working abroad?

You can only use the itunes store of your country of residence ( proven by the issuing country of your credit card and the valid billing address on that card). You must also be inside that countries borders.

If you are in another country and have a cc issued from that country with a billing address in that country, then change your information in your itunes account.

Every time I"m on I-tunes my internet stop working,causing me to lose music I"m downloading
