Transaction haven`t got 5 days ago some Pokerroom sent to my Bitcoin Core wallet a slight amount of bitcoin. I checked it on Blockchain, it's OK. But, unfortunately, still there is no bitcoins in my wallet. I've also sent email here - contact@bitcoincore.org with explanation of the problem. 

Who's already gone through situation like this please give me advice on what to do.

Many thanks,
Kirill
Your Bitcoin-core wallet will need to finish syncing with the network before it will display your balance.
