Okay bare with me if it doesn't work for you, seems to have mixed results.
1. Download and unzip this file: Attachment 16471
2. Move the english.Gadget
file to C:\Program Files\Windows Sidebar\Gadgets (NOT SHELL:GADGETS)
3. Open Gadget Gallery and run it.
Again, if it doesn't work sorry but it seems to have mixed results, if i turn it into an installer it doesn't do a thing, so I have no clue whats up with them.
