I'd try just starting again. To save you starting the whole blockhain again just download the bootstrap(see quote)...its the blockchain up to date to about 2 weeks ago.

First close your TRK wallet, then download this...


...then extract/unzip the bootstrap file to your Truckcoin roaming folder...then delete everything in the Truckcoin roaming folder except for your wallet.dat (do not delete this - you will lose all your coins) and the bootstrap.

....the restart your TRK wallet and hope.
