Update not available from 1.0 to 1.1

Hello, I'm uding the Bold Photography Pro theme without trouble. There is, however, an issue with the update from version 1.0 to 1.1. When I have WP run this I get an error message telling me that the update package is not available. Since everything is working well, this is not a big issue, though I would be more comfortable with the most recent version. Thank you!
