Hey so I bought psu last night with my pre paid visa credit card, it worked no problem and it downloaded, then in order to play the game online you need xbox live (sliver or gold) as well as something called a GUARDIAN licence, I have a gold account. Anyway moving on bought the game installed it and the expansion pack did all the updates went to go online said please buy a guardian licence bla bla bla, so I clicked buy (it was 14.99) and selected my pre paid visa and it came up with an error Status code:80190821! So at first I figured, maybe you can only buy games with pre paid cards and need a full credit card to pay for a monthly bill. So I used my best friends credit card (with his permission of course) cause he currently has a GUARDIANS Licence on his xbox live account and pays for it using that card, so I know it works, but guess what same status code! I did some googleing and at first it looked like we were just entering our adresses wrong, but we matched them EXACTLY and it still wouldnt work! Apon further reserch I found out people use to get this error when trying to buy xbox live gold account for family, then even further research I found out that others are having the same problem with PSU so I called xbox support 3 times, all three said the same round about thing that they had no idea what was happening and to try again later, it is annoying and such so could anyone post a way to fix this?
