I bet this is affecting all Brazilian players since Steam changed it's currency method to Brazilian Reais and now we, Brazilian players are receiving the "(ERR-19)" whenever attempting to buy Turbine Points from the ingame Store, option that I've always opted instead that getting the code from the site.
While I'm waiting the "You should contact Steam support" from Turbine, I'd like to let them aware of this if they weren't already.

Steam announcement to change the currency to Brazilian Reais:
I'd like to know if anyone is having the same issue and if there is a workaround for this. One option that comes to mind is copying the game data to outside steam and see if the ingame Store redirects me to Turbine's directly, where I could use my International Credit Card instead.
