From my reading on Cydia, the main theme, "blAze iPad" has not been updated for iOS 6 (there has been no update on the theme since May 2012). The odds are that if the main theme is not updated, neither are the different colored sub-themes, such as the red one.
I'm afraid that you'll not get this theme to work. So, my recommendation is to remove the theme or find out how to modify all the theme elements to make it work for you (as in: upgrade the theme yourself using a photo-editing tool like Photoshop).
Sorry, but oftentimes, themes just don't get updated...
