Can't donate please help

I bought a prepaid visa card last night and can't donate because the website seems to think I'm in Europe. The only choice I'm being given is to donate in EUR. I live in America/California and am not using a VPN. I changed the timezone in my Warmane account but that didn't help so I need to know what can I do to solve this problem?

Currency is not the problem. It gets converted automatically when you donate. Donation amounts for most payment methods are in euros for everyone.

The card says it can only buy things in the united states could that be the problem?

Yes, that might be the problem. Also you need a card that can be used online.
