I downloaded the wallet this morning... A friend sent me 100 rubycoin and I put 1.8342RBY on it....

but I tried to skate and he said I dont have mature coin

I never skate before, this is my first time... need some help..

And also .... something happen... I keep my wallet open for the stake and a mysterious transaction appear... someone took 100RBY ....
But when I go in the console... the message said:  12:56:18 Wallet is unlocked for staking only. (code -13)

Hope I can get a answer fast

thanks
