AssetStore image preparation problem...

Hey guys,

I was preparing a package that I have made for the asset store.

I downloaded the asset store tools, and i was following this tutorial: http://blogs.unity3d.com/2011/05/17/how-to-submit-content-to-the-unity-asset-store/

I downloaded the image templates that were in the tutorial from http://files.unity3d.com/will/keyimages.zip

but when i go to the assetstore tools bar at the top, and then select package manager, i prepare my package, but it comes up with a notifier that says: "Wrong bit depth for '/Pause Menu/AssetStore/small.png'. Must be (200x258 32bit rgba)"

It does the same for the "big.png" as well. I did take a look at the image properties and the small and big are 64 bit for some reason, but the medium and icon are 32bit, but i clicked on "Preview" and it showed an example of what my project would look like in the asset store, and all the images were there and fine.....?

Will i need to make the small and big images again.....??

Thanks
