DVD Architect 4.5 missing "Insert: Submenu from file"

[sir_rob]

I am trying to use a Photoshop file as my menu, but the only thing that I can do with the .psd file is set it as the background media. This gives me the background only. When I click on "Insert", I have an option to insert a submenu, but I do not have an option to insert a submenu a file.

The 4.5 manual states nothing about inserting .psd files, but the 4.0 manual does! Did Sony remove this feature? It is not in the help file or anything else that I can find related to DVD Architect 4.5. I have found that feature in tons of the other manuals as well. Is there something that I am Missing? Thanks for the help! (I tried to post this on Sony's forum, but was not able to as I have not yet registered my product--I am using the downloaded full trial version until my package arrives)

I have now posted on Sony's forum too, but have not received any responses there either. I suppose I will have to find a way to call them unless anyone has any insight.
