FSX is in english, will they be compatible?

Now why would you go and do that?
Take it back and exchange it, if it doesn't support multi language.

Its a present I got from South America

[Brett Hill 2]

ouch, I wouldn't be sure what to do in that situation. Loads of similar things happen to me with relatives in other countries they send things which dont match our needs

[Keep It Simple]

Perhaps if you called MS and explain the situation they would possibly let you exchange it for an English version? It's worth a shot.
