Seems like a silly question, but I searched this forum, searched bitcoin stack exchange, searched google, and didn't find an answer.

I just upgraded to 0.6 and after the block chain downloaded I tried to create a new key to receive BTC. It asked me for my passphrase, and I entered what I thought was the correct phrase (several times), but it didn't like it. Not to worry: the wallet is empty--I just needed to decrypt it to create a new key. So I can just throw the wallet away and make a new one (and make sure that I enter the passphrase correctly and that it works). But how?

Bounty might take a couple hours, but it'll be paid.
