1.Do you mind sharing your address so we can confirm you actually have money in it ?
2.As recommended above try updating your wallet to 0.5.19.
Other suggestions which you could try even after updating if your balance is not shown.
-Make sure your computers clock is showing the correct time.
-Try resetting a couple of times more since reloading the blockchain takes time.I had the same issue I rest the Block chain and Transactions for about 5 times ,finally worked.And its advised to do it like 3 times at least.
At last,this your last option .Let me know if you're willing to use Electrum ,I will link you to a procedure to import the keys .
As a last resort you can attempt to "sweep the balance". This involves exporting your private keys without password protection into another wallet application and then using that application to send the entire balance back to MultiBit Classic using a fresh wallet.
We consider this a last resort because private keys stored without password protection should be considered compromised. Malicious code on your computer could steal or copy the keys and spend the balance.
If you decide that this must be done then make sure that you don't use the private keys (and their associated addresses) again. We don't advise deleting them, just mark them as "DO NOT USE" in the wallet with the problem. That way if someone does happen to send bitcoin to them you still have the private keys to sweep the funds into a safe wallet.
