A few questions about setting up CP

Hello all, i just bought CP and i am setting up the stuff atm.

I got a few questions so far, hopefully you guys can help me:

1) When i click the link of a coupon, it goes to a 404 site (while the code popup is working fine). How to fix?

2) Where can i rename texts as ‘Latest Coupons’ (up in the screen, mainpage)?
