wordpress.com stats plugin not working?

Hi,
I’m getting the following message for my stats:
“Your WordPress.com account, “account name” is not authorized to view the stats of this blog. Currently access to stats is broken for some users and we are working on fixing this. Your stats are still being counted and will be visible once we restore access for your account.”

I’m using the wordpress plugin by automattic for stats and I got this yesterday and the problem corrected itself but I’m getting it again today. Does anyone know the reason for this or have any suggestions? I’m getting some traffic to my site and would really like to look at the stats…

Thanks.
