When buying the game on humble bundle i keep getting error message saying my currency is not correct. How do i change it?

[Dunpeal Hunter]

I am trying to buy the game which currently is on discount on humble bundle, but i keep getting the same error:

To Use Humble Rewards, Your Wallet Must Use The Same Currency As The Store You're Visiting.

What can i do to get rid of that error message, and buy this game? I have not seen any ways to change my wallet currency from Dollar (which it currently is) to Euro, which is what the game is priced at.

You had to manually select your country, which sets the currency used from the 2 or 3 available ones. If you have a mismatch, then you purposely set a different country than you reside in. It cannot be changed later, you must contact Humble support to do that.

Huuuuuge necro here, but I have my country set to the USA and the currency is set to USD. Humblebundle is still telling me that the currency is invalid. Did we get invaded and taken over recently? I don't watch the news.
