Enter your transaction ID in the search field at the top of any page on 2Masternodes website. Your statistics page will show up. If nothing was found please check the blockchain of the coin you've invested in.
Every coin has it's own blockchain explorer. Do you see the transaction on the blockchain? If yes -> just wait for some time. The service needs some amount of network confirmations to proceed with your investment.
If your transaction is not found on the blockchain there is a problem with your wallet. Most likely it has not been synchronized yet.
