This is actually an issue with the way that SQL Server stores the hashed passwords. Not all characters can be copy/pasted directly from the field. The workaround here is to log into your site and browse to the account.aspx page where you can change the password of your account. Update the password on the page and click the Submit button (you don't even have to change the actual password...just retype and submit). This will cause the password to rehash in the database. Try that password, and if that doesn't work...wash...rinse...repeat. Should only take a couple tries before you get one with characters that can be correctly copied from the table
