every time i try to enter my card it tells me check the info you entered it doesn't match...

Hello, iva Y. I'm Arturo, and I'll be glad to provide assistance with your inquiry today.

Where are you from? Just your country.

Did you try adding a different payment method if allowed, like PayPal?

Could you review if your Xbox region is the same as your physical location?
This can be done by opening Settings > System > Language & Location.

Yes, it is important to know that. Microsoft changed the way purchases work.

Hi, Iva.

I want to let you know that bypassing any kind of geographical restrictions to get content not available in your country is against Microsoft terms & conditions.

I don't know why you're able to purchase content with your other Microsoft account, but please be aware that a Microsoft account could be banned for this.

Besides that, in order to purchase a content in a specific marketplace and despite being physically located in that country, you need to use a payment method billed and issued in the same country.

For example, if your Microsoft account region is US, to purchase in the US marketplace you need a card from a bank in US.
Please be aware that cards from other countries, even with international use enabled, will not be accepted.

Without meeting these requirements, it is not possible to get content.

my country isnt on xbox so i cant select it and on my main account i can easily buy with my card while my location is set to some other country but i cant on the new one

Since Latvia is not supported by Live, your account region is most likely set for a different region. Since the credit card wouldn't match that region, that could be a possible reason.
