When I bought New Vegas I accidentally bought the spanish version. This wasn't a problem, as I am from Brazil, so I speak portuguese (if make any english mistake, sorry), that's very similar to spanish. After getting all the achievments in the game I decided to buy the DLCs, but I realized that just 2 DLCs are available in spanish (Dead Money and Honest Hearts). As I want to have ALL the DLCs, a friend of mine borrowed me his english version of NV. I didn't played the game yet, because I'm affraid that something can happen to my old saves or my achievments. Playing the english version of the game will reset my achievements or/and my old save files? Can I load and play my old saves (the spanish ones) with the english version of the game? If I buy the DLCs in english, they'll affect my spanish version (like, crashing or deleting my saves, any problem that may occur, I don't know)?That's all, thanks four your help. (= (Again, sorry for any english mistakes, i'm brazilian).
