Thanks for the update, Tom.
This post made me realize I have a forthcoming issue: I'm moving this July. I had the foresight to have the 2012 premium sent to a permanent family address, but this didn't occur to me when entering information for the 2011 premium.
I hate to be a needle-in-a-haystack bother, but if Tom (or anyone who has been in a similar situation in the past) has a suggestion on how I could go about correcting this, I'd love to hear it.
