Hello!I have some problems with mining....

I did everything,as Sarah said in her tutorial.my CPU is 100% busy,but i dont see any changes in my IoP balance and i don't see my address,when i write -IoP-cli dumpminerstats.Where is my mistake?
I have similar problem,I was lucky and already mined few blocks, but I don't see my address in dumpminerstats too.
Other problem I have is, one wallet is getting blocks, but the second one can't find any in a 3days.
I have two whitelisted addresses, but second one won't work at all. IoP.confs are exactly the same the just changed address.
Also tried add port 4848, or 14778, typed generate 1 in console, tried two machines with Win7 and Ubuntu too,
but still can't make it work, Can someone explain what is going wrong in here?
