ITunes won't accept my card?

So I've just recently gotten a new iPhone and things where fine on it as far as iTunes goes. But out of the blue one day I couldn't update my apps our download free apps, the reason being is that for some reason my card is being declined, which makes no sense because it's just a debit card and it definitely has money on it.

How to hack/glitch through a Windows Work Computer? (Details)?

I work at a call center at a law firm (Ironic huh?) and I was wondering if anyone could help me out with an issue regarding the work computers there. Life is slow in the call center and they have the operating system pretty locked up. Whenever you try to run something like [Windows Key + R], this sort of thing pops up: How to hack glitch through a Windows Work Computer Details

There's a flaw in the system however. Whenever I plug in a USB drive for the computer to access, they've tuned it to the point where the computer won't recognize the USB drive. However, when I plug in my iPhone to charge, an explorer window pops up asking if I would like to view the files on the device. Apple keeps the files on their products pretty hidden. So the system will only let me view the photos I have on my device. I tried to find the specific folder where the pictures are shown but I've had little to no luck at all. I was looking for the folder to put in a portable web browser that I could have dragged into the documents folder of the work computer and I could have accessed on a daily basis whilst being sneaky. I can't use the command prompt and I can't view files in the hard drive of the computer as this message pops up when I try to access the "C:" drive: How to hack glitch through a Windows Work Computer Details

Basically does anyone know of a way that I could maybe try to sneak a portable web browser onto the documents folder of the computer. The system runs Windows 7 pro. I can't use the run program, control center, ect.
