Ah, I see my answer was written in haste. The .csv export does allow you to export your stats, but only up to a year ago, which would explain why it's only going back to July 28 2010.
While we should probably consider changing this, the only way to get all the stats at this time is by manual export. If you wish to have this, please email me at sam@twittercounter.com.
