BuddyPress.org

Hello, Im Actually new on WordPress, and I’ve been working on my web page which is http://www.elparchestereo.com and the thing is that i saw your plugin and I thought that’s actually what i need it, because my web address is about a Radio Station, and what i want is to have like a socal site , that all my listeners can register and be there, do like a regular social media, and i have few questions to resolve that I haven’t been able.
first is that,when that ppl register and comes out the message that check the email to activate the account, i want that message to be in spanish and english, how can i translate that?..
Second: when the ppl recieved the email and clicked where it says to activate, it automatically transfer to a page that says 404 you got to the wrong place …. something , something.
How can i fix that?..
And Also I have this message on my desk “Each BuddyPress Component needs its own WordPress page. The following WordPress Pages have more than one component associated with them..” How can I fix those components, how its supposed to go, because i tried and that just made a worst mess, and since then i havent been able to fix it, i think thats the main reason for everything.

Sorry for so much, but I dont have anybody else helping me with this and i have done the best i can fixing my page , but this has been making me crazy trying to figure it out.

Thank you!
