I am unable to get HUB to use/refresh/update my EC2 Access Key.  I recently was in a situation where I needed to cancel my Hub/EC2 plan and then a few days later re-enable it.  I also decided to rotate my Access Key.  Hub is now reporting my access key as inactive, however, I have renabled it on EC2.  I am also unable to change the Key.  When I enter the Key and the Secret and click "Update account" the form simply does nothing.  When I return to the HUB management interface the Access Key is unchanged.
