If you are having trouble with your wallet, go to your app data folder and delete the library. Then download and reinstall the Client. If you want I can take a look at your wallet.dat file, sometimes it causes a bug with synchronization of the wallet. I can compile the file for you for a small fee, Im here to help.
please! never send a wallet.dat file to a person you dont know! it is most likely you will never see your coins again!
