i'm new user at desktop wallet xrp

[mxsx2904]

first i have new and empty wallet 

i ask my friend to send me 10 xrp

only to see if everything ok

but i didn't see anything 

so the question is why

maybe i must get first 20 xrp for active the wallet

and then i will see the 10 

or maybe its ok to just make new transicatoin of 10 xrp

and then i will see the all 20

i need your help 

thank you
