be sure your wallet are unlocked and fully sync. i got the same problem a day or two ago and i just unlocked and sync my wallet and the coins shows up on my wallet.
I am facing the same problem. I just installed the raiblocks wallet and copied the address and I used it to claim in faucet. So is there something more to do prior to claiming faucet?
Check your address in previous distribution (6.5 hours ago)
https://raiblockscommunity.net/faucet/distribution-single.php?did=1486425603
If you are claiming less then 6.5 hours just wait for next distribution (it's daily, so 17 h 30 m remains)
If you find your address in previous distribution, but didn't receive Mrai yet
Make sure your wallet is not locked (Status: password empty or Status: Running)
Advanced -> Block count. Check block count at https://raiblockscommunity.net/ (e.g. 269,794) It should be the same
Advanced -> Peers -> Refresh and make sure more then 5 IPs are listed
