Configuration problem with TXB 2D and Visual Studio (I supose...)

Hi,

I have a test C#-XNA project based on the 2D engine of Torque, and TXB, and also the platformer kit.

I have built a little level with some textures and animations, and also an actor, that can jump, walk, attack... until here, everything fine.

The problem now is that when I drag & drop any animation or texture on my scene, and then I try to compile the game, the dragged texture is not being rendered at the compiled game!! And I don't know why, because some days before it was working...

¿Some idea?

Thanks
