First of all, "Animate" should not be called in the main loop, but only one time, eg. right before the main loop starts.
Blitz doesn't support other X meshes than directX7 X. They only support rotate/move/scale animations of child objects. Bones or Vertex animation is not supported.
It may be most productiv if you use UltimateUnwrap3D and convert the animated X to animated B3D. You may be able to try it with the trial version, then buy it if it works. It is BTW also a very useful tool for UV works, and probably the only one that is capable of importing animated B3D.
You may also try to save 3ds in Blender that doesn't use any other animation than rotate/move/scale animations of child objects. I'd suggest to use other model viewers that are not based on blitz to make sure the animation is stored correctly at all.
