Ensure you have the current wallet version!
basically:
1. Backup your wallet
2. Run quarkcoin-qt -salvagewallet
This will take a while. After it completes your unconfirmed transactions should appear as unspent again.
3. Resend the coins in smaller amounts. The new version of the wallet should warn you if the transaction is too big.
(save your wallet in same way as bitcoin, click file icon and save, save as : wallet.dat
also there is a new wallet version out, so once you have done new transactions and sorted this problem. download new wallet and add saved wallet.dat by uploading)
