This was the way to go for Antcoin, probably still the same procedure:
9. Claiming your AntCoins
Once you have funds in your wallet you are ready to claim your AntCoins.
click on "Advanced" -> click on "AntCoin Claim"
You will see "available" and "unavailable" amount of Antcoins. The button "Claim all" will be greyed out.
In order to get your "Unavailable" amount to "Available" you need to transfer your AntShares to your own address.
Go to the tab "Account", right click your AntShares address holding funds. click "copy to clipboard".
Now click "Transaction" on the top of your window -> click "Transfer" Click the "+ sign" to add a recipient. Select asset: AntShares Pay to: paste your address holding your funds Amount: enter the number of AntShares you are currently holding in that address. Click "OK"
Note: you can just send 1 AntShare your first time, if you just wanna test it out.
Once the transaction is confirmed (see "Transaction History" tab) go to "Advanced" click "Antcoin Claim".
You will now be able to claim your available AntCoins and they will show up in your wallet.
Repeat step 9 to claim newly generated AntCoins.
