This is regarding 1BWxWrPxVcGvYLS4E6kdMEKDmNhPWxtNT6  ?? dumpprivkey also worked for this address?

Do you have an old wallet backup? I suggest creating a backup of your current wallet.dat file and then replacing it with the old backup. Then see if your coins show up. If they don't do the dumpprivkey command for the change address (1frs) again to see whether it shows up using in the old backups.

Location of wallet file: https://en.bitcoin.it/wiki/Data_directory

Sounds quite strange.

Like Abdussamad said I would try recovering from a back up.

If you sent that 0.1 BTC then the rest of it went to a change address which your bitcoin-qt client will have the private key for. If Not then i'm not sure what has happened but I guess it might be a corrupt wallet so isn't able to pull all the private keys out of it & thats why your balance is wrong.

Ok, thanks everyone, will try the backup.
