Something must have gone wrong with your transaction I'm afraid, we've had about 40 blocks in the last 48hrs - still a lot lower than it should be, but txes only need 10 blocks to confirm so your SPARK should have reached BTER. If you find your tx id you can use the "Block Explorer" in the Windows wallet to check whether it is in the blockchain. Otherwise it may be that your wallet is out of sync - at the time of writing we are on block 24614
