Status Code: 80190848

This code suggests that you owe money.  Check your billing info at billing.microsoft.com.  If it can't be fixed from there, you'll have to call support and ask to speak with billing to get it sorted.

I don't think I owe money because I just added the credit card today. I think it may have to do with the fact that the card expires soon? On Microsoft it says "expiration pending". Does that mean I can't use it anymore?

It is a possibility.  However, the code does mean that purchasing options have been locked for you and you will need to call support and ask to speak with billing about it.

oh okay, well thank you anyway :) Do you happen to know when the 2 months for $2 deal ends?

I don't know when that promo ends but if you read the small print of it you should find the date there.

Thanks. If I go out and buy a card for MS points can I use them to buy a Gold membership? If not, is there any way I can get a 1-month Gold card from the store? I've never seen them, do they exist? I can't afford the 3-month and 12-month cards, I'm a teenager and I'm using limited left-over birthday money hahaha

I don't think stores sell 1 month cards and you can't get gold using points yet that I know of.  However, a 3 month or 12 month card is actually cheaper than getting 1 month at a time.

I know, but I have enough for the 3-month card, but probably not plus plus tax :/ those little differences really suck sometimes :( I just want Gold, I hate dealing with all this, sooo complicated.

I'm getting the same error code on an account that's brand new, with exactly the right amount of money in it to buy the 3-month offer that's on the Spotlight channel - did you find out what it was? I'm thinking some kind of glitch with the Marketplace seems likeliest... =/
