Help, I can't select an uploaded VHD file

I activated my MSDN Pro subscription for Windows Azure.

I found documentation on how to build and prep the VHD file with an operating system.

I followed the sysprep and was able to upload the vhd file.

Using the Windows Azure Explorer, I can see my vhd file in the container that I added to a container that I created

When I go to Virtual Machine to add an image, I go to browse for the vhd file in that same container and it won't appear.

Is there something else I need to do for that uploaded vhd file after uploading?Thanks in advance,

Bob
