    settings\administrator\application data\bitcoin\database! To recover,BACKUP THAT DIRECTORY,then remove everything from it except for wallet.dat.

    Are you sure the message was not telling:

    <pre> Error initializing database environment C:\documents and settings\administrator\application data\bitcoin! To recover, BACKUP THAT DIRECTORY, then remove everything from it except for wallet.dat. </pre>

    Btw. please close the other double-post, thanks.

    The error message can hardly be any clearer in what you need to do, can it?

    yes, this is what it is saying

    Error initializing database environment and settings\administrator\application data\bitcoin\database! To recover,BACKUP THAT DIRECTORY,then remove everything from it except for wallet.dat.

    The message is clear enough, but it doesn't explain what happened. (For me, it was after migrating my stuff to a new machine and downloading and running the 64-bit bitcoin-qt 0.8.1.) I'd really rather not reinitialize my blockchain, so a hint as to what has happened would be great.

    ETA: I found more info here:

    If you were running on Linux with a version that might have been compiled with a different version of Berkeley DB (for example, if you were using an Ubuntu PPA version), then run the old version again with the -detachdb argument and shut it down; if you do not, then the new version will not be able to read the database files and will exit with an error.
