Help with SkeletalMesh errors

[SabreFox]

I am new to UDK and I have read a lot of the tutorials and watched all the 3DBuzz videos but when I decided to stick a few SkeletalMeshes in the level I was making I get the error:

SkeletalMeshActor casts a shadow but has not PhysicsAsset assigned. The shadow will be low res and inefficient.

I looked at the properties that would hopefully fix this and nothing I seem to change makes this go away.

Example, I use UDK's Scorpion mesh as just an object in the level for the player to see and not use.

Under Collision I have: Block Rigid Body, Can Step on (checked)
Collision Type COLLIDE_BlockAll

Under Movement I changed Physics from PHYS_None to PHYS_RigidBody (thinking that would make the issue go away)

Am I miss a check box somewhere in the properties?

Thanks in advance for any help.

I am still having this problem and am about to just ditch the idea I had with using these meshes, any help would be greatly appreciated.

It's not an error, it's a warning.
The skeletal meshes included in UDK gives the same warnings. So they are nothing to worry about.
