Wallet wont sync completely

Hello All
I am a bit of a noob with this stuff but I started mining ppc again, put my address in and been mining for a while but I had an old peerunity wallet which would not sync so I downloaded new wallet put wallet.dat file in there and started to sync but seems to stop at 26 weeks I have tried twice and still stops there.

Many thanks for any advice

Are you running the latest version?

yes

Make sure you dont unlock your wallet for minting until it has finished syncing. If that doesnt work, make sure you still have the wallet backup and delete the whole folder, open the client fresh and wait for it to sync from scratch, then replace the wallet.dat file and open with the -rescan tag.

Thanks its up and running I was unlocking for minting.

Many Thanks
