    I upgraded my bitcoin client to 0.6.3, but when i open it it said ' error loading blkindex.dat' . Could some please tell me how to fix this? Also will my bitcoins be lost from the previous bitcoin client?

    Your bitcoins should not be lost. You should, however, always make regular backups of your wallet.dat. Before trying to perform any further repair you should go and make a wallet.dat backup on removable media. You should also make a backup of the whole bitcoin directory for extra security.

    After doing that, if you delete everything except wallet.dat in the Bitcoin data directory you should begin running again. I can only guess that perhaps you did not shut down Bitcoin cleanly before your upgrade.

    What platform are you on? Windows, GNU/Linux, Mac, other?

    Windows

    You should be able to plug %appdata%\Bitcoin into explorer to find it.
