Assertion error in animation library: Number of matrices registered is equal to the max number set at creation time

Question

When I replace the tiny_anim.x animation file with another one in the DirectX multianimation demo I get the following error:

Assertion failure! (s:\gfx_sdknovember08\windows\directx\dxg\d3d11\d3dx9\anim\loadxh.cpp 1392): D3DXFrameNumNamedMatrices(pframeRoot) == plc->cNamedMatrices
D3DX: ID3DXAnimationController::RegisterAnimationOutput: Number of matrices registered is equal to the max number set at creation time.

This is only with some exported models and not with all.

What could be causing this problem?

You're using the November 2008 SDK? Try using the March 2009 SDK (or August 2009 SDK if its out by the time you read this).
