Swap had a long time ago.
Unfortunately you have lost your coins.
See OP for more information and also the previous topic.
I dont think he is talking about sum v1, just an older version of the wallet
In any case, first thing is to download new wallet and blockchain.
If the block explorer sees your coins in your balance, that's what you should believe. The rest is just local problems in your computer.
I'm sure you'll see the coins once your wallet is setup again
