    @metbit: these messages are normal, like it says in the post. Wait for better peers (not everyone has upgraded yet).

    With eth, I'm getting lots of messages like:

    I've deleted the blockchain (or at least what I though was the blockchain - a folder named with a string of letters and numbers in .ethereum) and it still does it!

    Hi, did you backup your data directory before upgrade?
    http://ethereum.gitbooks.io/frontier-guide/content/backup_restore.html

    Look at the data directory and backup to another folder what's there before you try anything more.

    Post more info on what exactly you did. What OS version, etc. Maybe someone will be able to help you here.

    Peace.
